I flipped my longhorn.....she runs stock leafs, with the flat overload & 3 tossed off the bottom of the stack. The 12 bolt diff came from a 75 C-10 donor, & the pads needed to be replaced. I went direct connection (chrysler) pads, set the pinion angle & welded them on.After the drop, the spring hangers were moved down on the frame just a tad(1 1/4"), to bring things good front to rear. The front is a 1 coil cut drop (about 3"),'75 1/2 ton spindles & the body is dropped 1 1/2"(lots of work, but nothing makes sparks on the pavement
) best of luck,
