I remember the general layout, just don't remember if there were any specific details I don't remember. I know about Caltracs and Assasin bars, just like to be different ( or difficult) as my wife says!

You have to use a thicker main leaf spring - back in the day you had to use the 002/003 spring because it’s mainleaf was thicker than the SS springs. And you had to clamp the front segment at that. There are better designs now.

I floated the housing via an aluminum bushing that allows the housing to rotate freely. The bushing is a two-piece that I designed and machined myself. The leafs hold the car up, and the four-link seems to work.

Yep I can testify that is correct, I had a leaf link set up on a 66 cuda, and I bent the spring, when the spring bent it allowed the slick to rub the front of the fender, ruined the tire, and was lucky it did not wreck the car.

I know they are a bit more involved in set up and installation, but they are supposed to be way better than a 4 for going around corners This forum is mostly for straight line racing. In the cornering forum, the impression that I've gotten is that the cost and set up isn't a benefit until you have a dedicated race car, and then class limitations come into play. If I had unlimited (or a much higher limit) funds, I'd go IRS and get rid of the live axle.
