No, right now I'm running a stock 10-bolt (6-lug) in the front and a 14 (8-lug) in the back. This is for my '90 and I DO wheel it (not as much as I like). I have not broken anything in the front yet, but the 37's have to be on borrowed time up front....I would think. How hard will it be to find the hub/rotors? I'm not too worried about the rest. I didn't ask any questions when I picked up my 14-bolt and it was nothing as described. I figured this time I would ask before I picked it up.
