"71" Camaro Restomod 06B Driver Side Door Hinge Bushing Size Difference Solved 9-18-2020
I was a little puzzled about the different size bushings while looking at the lower hinge. Figured it out at the end of the video. Have no idea why GM decided to use different size bushings between the top and lower hinges. The larger thicker knurled bushings are used on the top hinge and the smaller bushings with the smooth outside bore diameters are used on the bottom hinge. Why GM didn't just use the larger bushings on both the top and bottom door hinges is a mystery. It would have made more sense strength wise and they would have had one less separate P/N for the 71 Camaro by using the same bushings everywhere.
