Rich made a jig fixture from an old floor pan to make a front subframe that uses leaf springs, but I'm not sure if he still has it. He's in southern California.
Strike Eagle did his many years ago using mostly stock Jeep parts. He doesn't do well with the internet, but he would be happy to tell you over the phone what he did. PM me if you're interested and I'll give you his number.
