I am restoring a '69 camaro, and have decided to convert it from a standard to an RS. Unfortunately, I am just starting and I don't know that much about camaros. I researched a bit on what I would need to get to make it a rally sport, such as hideaway headlights,emblems,chrome mouldings, etc. but when flipping through the classic industries catalog I noticed that in the "front fenders" section they advertise the standard and RS fenders as seperate things, but when I look at them it appears the rally sport fender is the same but without an extra piece. How are they different? My car is from new mexico (100% rust free) and my body is in great shape so I would rather not replace them if I don't need to.
