I am doing a 1972 Challenger right now. I began pulling it apart and have a question on the inner chrome rings. When I pulled all 4 of them off I looked at them and saw that the inner ring would either have 2 tabs (for the bolts) or 3 tabs. Are they all suppose to have 2, 3 or are they suppose to be different like that? Thanks ahead of time and what a great forum.
