When I disassembled my front clip and all the RS parts, I noticed the car had two different size (depth) Headlamp retainer rings. These appear to be identical except for the depth, and both/either work fine. One is approx. 13/16" deep, and the other is 1" deep. Which of these are correct? or did GM use both sizes interchangeably? One corner of my car was hit before I bought it in the mid 70's, so I'm not sure if both these parts are original from the factory, OR not. Your help greatly appreciated so I know which of these to replace..
