First of all, thanks to all who responded to my first question, it's really appreciated. O.K., I've decided to go with a 6" lift to go along with the 35x15.50 Mickey Thompson tires and 15x12 rims I just bought. I know I'll need new shocks, extended brake lines, gear change, steering arm and I'm gonna get the driveshafts lenghtened. I have two questions: 1. After getting the driveshafts lenghtened will I need to use shims to get the angle right for the u-joints? 2. Does anyone know where I can get the proper drive gear for the speedometer? I'll post some before and after pictures with the lift and tires and the before and after when I put my 383 under the hood. P.S. This is a great site.
