i have made a full floating set up for my 50 chevy and used comp ladder bars and used a track rod with stock 50 chevy springs this work good and takes the of the whined up out of the spring and works good and the ride is not to bad. i had lift bars on it and the ride is better with the ladder bars on it with the floating setup. roads are not to good in bay city and it is as good as my 90 chevy two wheel drive truck. if you do a four link i wound use a panhard bar or watts linkage the track rod on this type of suspension is not as good as the panhard bar it will keep the rear end from moveing side to side in a hard turn the panhard anchors the rear end to the frame instead of holding the axle to the lower bars there is to much flexs with this setup on the for link or ladder bars on the street .it seams to work good on my 50 the springs help keep the rear end in places side to side but i had the trackrod with ladders bars on a tub gto and i all most drove the car off a bridge with this set up .
