I did 4 link on 73 Dart with coilovers and used 150# in rear

'71 Duster 2860# (3100 with driver) ladder bars, Think mine were 120's, remember thinking that seemed pretty light, but they worked good. Best bet would be to call or email some of the chassis places and see what they suggest.

We use 110 lbs springs....but we are a couple hundred lbs lighter.....I dont know how much weight is on the rear either...

you need to know the weight of the rear of the car then call the shock maker. This will be impossible without four corner scales. There is another way to get you closer. btw 150lb spring sound way to stiff.

Use these two links to understand the concept

Since this is in the racing forum, I'm guessing this is a race only car? As said, you really should get the rear sprung weight of the car to choose a set of springs.
