We built a set like that with shackles on a blazer sand racer. Class had to have stock leafs. It worked like a charm with a big pontiac motor and clutch flite it would pack the front end unless it broke something which was most of the time.

I put it on another thread but I'm going to try clamping the front leafs with a plastic wedge between the overload and top springs to mimic the old mopar leaf spring. I've cut the back overload and the bottom two leafs off for a better ride. This is on the twd sb I am just putting together for the street. I may have to add one more long leaf to stiffen the pack up but I'm going to start with the stock leafs for now.
