Yeah, I just used 5/8" heim joints and threaded tube for the ladder bars and cut my brackets from thick wall square tubing. The brackets I welded to the underside of the spring pockets and the trailing arms. I used left/right threaded heim joints so that they're adjustable on the car.

The car really does hook, but still handles like a Chevette otherwise, for good and for bad. I'm seriously starting to consider airbags.
