I am going to have my ralley wheels powder coated, question is they currently have the shallow trim ring and shallow dish center caps, can I add the deep dish center cap and deeper trim rim as they look better, or do I need to get new wheels. The car is a 1969 Camaro SS with a 350. I am not opposed to getting new rims but don't know about the back spacing. The car is set up all original and goes to car shows. So if anyone knows what wheels it should have on it let me know, just not very well educated on wheels. Thanks, Jerod
