Spring relocation kit?
Tubing the car is dependent on the tire size. I have the springs move in on my Valiant and have the stock tubs in the car because I only run a 28 x 9 x 15 slick. The 9" slick fits in the stock tub fine so I left them in the car. I believe that a 10.5 tire will be about the limit of a stock tub.
