I am about to buy some wheels from a friend of mine. He has 4 17x9 black bullitts. At first I thought he just had 17x9s in the rear and the fronts were 17x8s but he has 17x9s all the way around. Anway, I have a quick question. I know the 17x9s should fit without issue on the back but I don't think they will on the front from what I've read. Is that true? Also, what is the widest 17" wheel that will fit on the front of stock 67-68s with out any modification?
