What do you want? Stock steel, fiberglass?

I would go with fiberglass but you also have to install gas shocks. You also have to decide what rate you want based upon the type of driving you intend to do.

Went with a 360 VBP monospring back in 1986 when no one was using them on my 78 L-82 gymkhana suspended car and have never looked back. I would not use a steel spring which is heavy, will sag, and rides harshly!

why do you have to install gas shocks??? I never did an my ride is great with a fiberglass spring. They did not recommend gas shocks when I called them to talk about the different springs, they reccommened stock Delco shocks for street use.

no not at all concerned with stock, plan to build the engine a little, has nitrous, TH400 + converter, 454,
only think I want to keep stock is the body/hood- been hard to find a manifold to fit it

I've had a fiberglass spring in mine for over 25 years, still fine. The original steel spring broke a leaf after only about eight years of age. You probably want special shocks for the different rebound rate. After several shock installations, I finally like the current setup with Koni's set one turn stiffer than mid-range.

If originality isn't important to you, don't even consider a steel spring. You won't believe the difference with the fiberglass. If the steel spring was any good, The General would still be using them.

I've got the VB&P dual mount spring.

It offers adjustable spring rates, ride heights, and also mounts to the rear cross member instead of the differential cover.

I've read about the "ears" on the differential cover breaking off in our cars, so I figured since I am going to replace my metal spring anyways then I would remove the risk of breaking the differential cover by installing the dual mount spring.

The spring isn't installed yet, but that will be the project this coming spring.

Hope that helps.
