Quote: I had a '72 Cuda I did with the Mancini kit and moved them inboard. After that, I fit a 10x28 slick or similar hoosier treaded tire. It was tight to the springs but I was lucky, I had just enough clearance and did not tub the car. Axle got new perches, and leafs got new hangers.
Stock axle width then?
Yes, just used wheel back spacing to squeeze them in there. Cut the old perches off, and welded new ones on. Double check pinion angle when doing this...
