1958-64 CONVERTIBLE QUARTER WINDOW INSTALLATION

1958-64 CONVERTIBLE QUARTER WINDOW INSTALLATION


This month's article will explain the preparation of the pieces for the installation and adjustment of the Convertible quarter window for the 1958 Convertible. Since all Late Great Convertibles have the same basic pieces and are assembled in the same way, this article can be used for any of the 1958-1964 Convertibles. Specifically, this article will explain the restoration of the quarter window pivot assembly, the installation of the whisker strips on the beltline stainless and the restoration and re-felting of the lower quarter window channel.

By having all the pieces collected and restored, the actual installation and adjustment of the quarter window is quite easy and does not take very long. That is why we have always suggested that during the disassembly of a particular part of a car that all the pieces for that area be placed in a box and left together. If you will leave all the hardware with a particular piece and all the pieces from an area in the same box, the restoration and re­assembly can be accomplished without the tedious job of trying to collect all of the parts. Often the time period between the disassembly and the re­assembly of the car can be a long time; thus this is a very good suggestion that will save time and money if you have to purchase parts that you cannot find.

The preparation of the parts for the quarter window installation is quite simple if you know what to do and how to do it. That is what this article is all about. Later this year we will have an article which will explain the actual installation and adjustment of the Convertible quarter window

Image #1, 2: Many of the Convertible quarter pivot assemblies that are found today have not been adjusted for years . As a result, the special bolt that secures the quarter window to the pivot assembly and the two special adjusting studs may have rusted into place. (See Photo #1.) There is no way you will be able to use the pivot assembly until these three items are removed. You will need to take extreme care in trying to remove the special bolt and adjusting studs. Usually through heating and the use of a solvent such as "Liquid Wrench," these can be removed. Do not be surprised if the special studs break off. If they do, you will have to carefully drill out the remaining part of the studs and re-tap the holes. The special studs are available as PIN 539109. (See Photo #2.)

Image #3: As seen in Photo #3, all of the pieces for the left pivot stud assembly are shown. Bead-blast and clear-coat all of these pieces. The threaded holes in the pivot assembly should be cleaned up with the correct tap: the adjusting studs are 5/6-18 and the attaching bolt is 3/8-16.

Image #4, 5: Temporarily install the pivot assembly onto the correct quarter window assembly as seen in Photo #4.Because of the new chrome plating on the Convertible quarter window base, the Convertible quarter window may not slide into place on the pivot assembly. (See Photo #5.) Use a flat file to remove any metal burrs off of the pivot assembly in the location where the quarter window will be installed. Use the flat file to remove any burrs and extra chrome on the Convertible quarter window.

The quarter window needs to have full motion around the pivot assembly until it comes against the stop as pointed out with the awl in Photo #4. Repeat the last three steps for the other quarter pivot assembly and then set all of these pieces aside for the installation.

Now prepare the quarter beltline stainless for installation. It is easier to polish the beltline moldings before installing any of the whisker strips. If the window felts are installed before polishing, the cleanup of the beltline stainless and whisker strips is time consuming. Steps 5-9 will explain the installation of the whisker strips onto the beltline stainless. You will want to work on a bench that has some kind of cloth cover over it so that the polished beltline moldings will not get scratched as you install the whisker strips. The greater the shine the easier to see small scratches. For extra protection, you can take some masking tape and mask off the polished surfaces of the beltline moldings while installing the whisker strips. When you have finished the whisker installation, removing the masking tape and cleaning the stainless with some 3M Weatherstrip Adhesive Cleaner (PIN 549009) is very simple and takes very little of your time compared to re-polishing any piece of stainless.

Image #6: Our window felt kits include pre-bent felts and the staples required to install the whisker strips. The kits even have a carbide drill bit that you can use to drill holes in the beltline moldings for the staples. The kits that are available for the Convertibles are listed at the beginning of this article. These kits include the pre-bent whisker strips for the doors and quarter windows and the hardware for installing them. In Photo #6 the quarter beltline stainless and the whisker strip pieces are shown. (Some beltline stainless moldings may not have the short piece of whisker strip.)

Image #7: Position the whisker strip onto the beltline molding and then clamp into place with a pair of vice-grips. (See Photo #7.) Check to see that the whisker strip is positioned flush with the front of the beltline molding. Using a sharp awl, find the pair of pre-drilled holes for the first staple. (See Photo #7.) Use the drill bit provided in the kit to drill the two holes in the stainless required for the first staple.

Image #8, 9, 10: Release the vice-grips and install one of the staples through the holes in the whisker strip. (See Photo #8.) Position the whisker strip and staple onto the beltline; then while holding the whisker strip firmly to the stainless, use a pair of needle -nosed pliers to pull the ends of the staple and to squeeze the ends together. (See Photo #9.) Finish installing the staple by squeezing the ends of the staple into place. (See Photo #10.)

Image #11: Repeat this procedure for all of the staples along the beltline stainless. Try to maintain the same distance from the top of the whisker strip to the top of the beltline stainless. (See Photo #11.) Repeat Steps 7-9 for the other quarter window beltline stainless molding. Set these pieces aside for future installation.

Image #12: Like many Convertible quarter pivot assemblies, the Convertible quarter window lower channels are usually in rough shape. A5 seen in Photo #12, the ribbed -metal inner channel is often rusted quite badly. Originally, the inner channel was felt-covered and spot-welded to the bottom of the outer channel. Depending on the condition of the inner channel, there are two basic ways of re-felting the lower channel. If the ribbed inner channel is not rusted too badly, channel lining material (PIN 536047) can be glued into place using some 3M Weatherstrip Adhesive (PIN 563566). If the inner channel is in poor condition, it is best to re move and discard the rusted mess. (If you are removing the inner ribbed channel, skip to Ste p 14.) If you are keeping the ribbed inner channel, proceed to the next three steps.

Image #13: Final Steps - If Not Removing the Inner Channel (#11-#13)

Remove the short pieces of whisker strip at the rear of the channel assemblies. Bead blast the channel assemblies and spray with a clear coat. Using the procedures explained previously in this article, install two new short pieces of whisker strip onto the inside rear of the outer channel. (See photo #13.)

There is no lining material wide enough that can be used to completely line the inner channel. Our lining material, PIN 536047 , is a little wider than 1.5-inches. Since the quarter window never comes in contact with the bottom of the inner channel, the only parts of the channel that need to be protected are the sides. A strip of the lining material will be installed on each of the inner sides of the ribbed metal channel. The edge of the lining material will overlap the top edge of the inner channel. Thus, the correct installation of the lining material will have it glued to the inside of the ribbed inner channel, over the top of the ribbed inner channel and glued to the outside of the ribbed metal channel. This leaves the overlapped piece of the channel liner between the ribbed metal channel and the outer channel.

Some 3M Weatherstrip Adhesive Cleaner (PIN 549009 ) will work very well in cleaning up the mess. Repeat the above steps for the other channel. Now the pieces are ready for installation 1 and adjustment of the Convertible quarter window assemblies.

Image #14, 15: Since you removed the ribbed inner channels, some heavier lining material must he used to line the outer channel. An auto trunk lining material, PIN 536013 , can he used to line this channel. This lining material will stretch and can easily be glued into place. It provides the required protection for the chromed Convertible quarter window assembly Determine the width and length of the felting material to be used.

There should be enough to cover the bottom of the channel, the sides of the channel and to overlap the edges of the channel about 3/8-inches. The proper length of the felting should be so that it goes the complete length of the channel and that there is enough left over so that it can overlap the ends about 3/8-inches. (See Photos #14 & 15.)

Image #16: Before starting this procedure, read the complete step. Each channel will be lined in three stages. Place the channel in a bench vice to hold the channel while installing the lining material. Using 3M Weatherstrip Adhesive, glue the felting into the channel bottom by working from one end of the channel to the other. Use a wooden paint stick, or even your finger, to apply the adhesive to the channel bottom. Work the felting into the bottom of the channel. Make sure that there is equal lining material for both of the channel sides. Add the adhesive to a couple inches of the channel bottom at a time. This will be a messy job, but it is just about the only way you can get the material into the channel bottom. Set the channel aside and allow it to dry After the adhesive has dried, repeat the gluing procedure for each of the channel sides. Finally, add adhesive and overlap the edges and the ends. By allowing each step to dry, the felting will not pull away from the bottom as you stretch the liner up the sides and over the edge. (See Photo #16.) Repeat this three stage procedure for the other channel.

Some 3M Weatherstrip Adhesive Cleaner (P/N549009) will work very well in cleaning up the mess. Now all of the pieces are ready for the installation and adjustment of the Convertible quarter window assembly
