Springs are 002 003, 71 Duster Stock class 340 auto. Ive used these springs on a-body’s and b-body’s before but just by themselves. I’ve always had the snubber slightly off the floor. My goal is to leave like ladder bars or 4 link instead of the housing wrapping up like a spring losing 60 and ET. [/quote]

Have you run the car yet? Those springs have a stiiff enough front segment that they generally don't wind up. The short instant center does tend to seperate the housing. What shocks? Get the rear rebound tight enough and it'll slow the seperation.
