I bought some sport wheel center caps and have a question. The one on the left has a retainer that I've seen on all the center caps I've owned. The one on the right side appears like it would be for a smaller diameter center hole. What do the wheels look like for the right side cap? Any info would be great.
Both fit same rallye wheel centers. 12 prong or newer 4 prong style retainers is the only difference.
They both suck AFAIK. Lost a few caps back in the day. I like the reproductions with the security bar that bolt on from the back. http://buickcenters.com/index.html
One is pressed together and will loosen up over time. I've drilled them and used small self tapping screws to keep them together. The older one is assembled with screws and I always had more faith in them.
The screw on retainer on the 71-77 are nice! They can be unscrewed and emblems can be easily replaced! The 78-87 can be drilled but is more of a throw away one!
