I have recently received a set of decent 70/71 SB rallyes with ok center caps. Three out of the four have some deep scratches in the center of the caps. I found these inserts advertised. 1970-1971 Rallye Wheel Center Cap Insert Set of 4 - Dante’s | Mopar Parts Catalog |Classic Muscle Car Parts Anyone have experience with this? Do these "pop" out? and what's the best way to do it? or is this some kind of cheap stick on trick.
