If I was going for IFS, I would use the 73-87 suspension and just buy inset rims so it would look stock. I think it would be best, besides I like the widetrack look .You could always get wider rims for the back to stick out farther.Personally I prefer the stock suspension. I just switched to a 76 Cutlass rear end and had my front hubs altered.Thet welded up the old stud holes and drilled new ones to match the 73-77 Chevelle and Cutlass patern, so now I can run Corvette ralley wheels. Oh, I used 55-57 Chev car wheel drums. Everything is as I want it.
