Differences in quarter window roller plate
Going through my parts and noticed a difference in the roller plates for the quarter windows. Curious why GM made the change.
The bottom plate in the picture is from a 1970 GTO and the back roller has a spring to preload the roller. The top plate in the picture is from a 1972 Lemans and it has no provision for the spring. Anyone know why they eliminated the spring? What does the spring even do? Thanks
