That front seat just won't go back quite far enough, will it? We must be giants compared to the back in the 50's... or we have all gotten a little bigger around the equator in our old age. Installing a tilt steering column can make things even tighter as they are slightly longer than the stock column. Or you have a floor shifter that hits the seat and you just don't want to change shifters or modify the seat. A simple solution is to relocate the seat further back in the car. But, if you move the seat back on the floorboard, the rear legs of the seat tracks will drop off the seat and lean to the rear. Plus, new holes would need to be drilled in those nice stock floorboards. Classic Chevy has developed a simple bracket system that bolts to the floor using the stock mounting holes. The seat will be relocated toward the rear of the car by 4". Best of all, no new holes will need to be drilled in the floor.
