Review shared from 1968-1981 Corvette Transmission Slip Yoke. 32 Spline - with Attaching Hardware
1979 Base - UNKNOWN
A great deal for me.
I am collecting parts for a 4 speed conversion package for my 86 el camino. Most of the parts are used or refurbished anyway. That the driveshaft can be disconnected from either end with this yoke is a win, win.

Clutch Fork Boot
I decided to replace the clutch fork boot at the same time I installed a new clutch fork. The new boot fit perfectly. It also seemed to be made of much heavier material than some of the others.

Great Clutch Fork
I purchased a new clutch fork for my C3 Corvette. It fit perfectly and the clutch is back to working great! I can always count on Ecklers for parts that fit as they should, work flawlessly and look great!!

chrome shift knob
I was surprised and impressed with the fact the knob was actually chrome plated metal and not plastic. The price was very fair for the quality.
