Yes Tim most did, and the ones that still exist (very little I might add )have steelies, however many had rally's all the yenko copos had rallies and lots were sold in like 1972 throughout 1973 at dealers with 5 spoke mags. You have to think the COPO ZL1 was literally priced twice the price of a base model V8 with options. This made them extremely hard to sell, so 5 spoke mags were an attempt at selling more, lots were sent back to GM as I understand. Again I'm no expert I was just being conceived at the time.and let's also remember that out of 69 total production I think only six exist in the registry. One # 48 the most original is in Canada, and is the only one in that country. This model has to have some of my imagination in it , or it just wouldn't be quite as fun.?
