It seems pretty easy. You put the front part of the leaf into the lower cotrol arm shackle. For the back either run a large bolt throght the frame or make a shackle out of heavy walled square tubing. Always use grade 8 hardware. There are some different methods to make it stronger like flat stacking and using shorter home made leaf packs. Depends on what your rules allow. I'm not an expert on this topic, I havn't done this to one of my cars yet. I'm thinking about doing it to a bubble gm wagon to run in my local fairs. Around here they allow you to convert 80 and newer cars to leafs if your willing to run with old iron in fair class. hope it helps.

To flat stack you take the leaf pack apart and flip every other spring upside down, use a lot of spring clamps when u do this. And ya just weld them to the rear end.

I wouldn't ever weld leafs to a rear end housing. Spring perches are dirt cheap. Make a plate out of 1/4 inch steel to run the U-bolts through.

u can weld springs together.dont really like the flip every other spring method make the leaf springs flat (roller or a press will work good) i use a roller cause i work at a weld shop. i like makeing my own leaf spring mounts front and rear dont care if the car came with leafs redo them. unless they are mounted under the frame allready or use the lower controle arm mount spot on the inside of the frame. i run mopars so i relocate the leafs under the (frame) in the back
