Thanks Chryco, I guess i will be the Guinea pig!
I am pretty sure that I am going to have to send the Wilwood rear kit back to Mancini. I told them that I wanted the kit that fits the stock 15" rally wheels. They sent me the 12.20" rotor disc kit.
So I might go ahead and order the Dr. Diff kit and call it a day
I was trying to use the same style calipers all around but since im sticking with the rally wheels it won't matter if they are different & I mix & match. I think i am sleeping while typing I'm sorry if this post doesn't make any sense lol!
