Using a B body 8-3/4 rear end in a Duster.

Axle wrap is extreme and I'm hoping to reduce this with a snubber.

Would clearance be an issue with an aftermarket snubber, like MP's or Mancini's? The Mancini piece looks like it is worth the extra $20.

Put the right springs on it and use the pinion snubber for what it does best. Door stop.

My racing budget, what's left of it will not take the hit.

If I have a budget of 150$ (race winnings) and bad wrap I'll have to pony up for the snubber or maybe scrounge up a set of traction bars.

The car had this old setup seen below. The bottom leafs are only halfs with a pad at the end. Where they bolt on can be adjusted as shown below.

Go the traction-bar route before the snubber

As long as the existing wild spring setup is anchored, and not ready to fall apart, you can put the adjustable snubber on it and adjust it 1/2 inch from floor and try it. You will be greatly annoyed by the street manners after that though.

Back in the mid 80's, I didn't have much money and ended up useing 3/4 ton chevy truck springs mixed with the originals. The springs were 50 bucks at a junk yard, and new center pins. I ran 8 leafs on the left and 9 on the right. In front of the axle and 3 leafs out the back. I kept the first leaf stock, then added every other truck leaf. Being sure to stagger them 2-3 inches back with each leaf, for the first 4 or so. Didnt even need a snubber and ride height was about 1 inch higher. I used a 069 J converter and 391 gears in a 72 cuda with a 9-1 comp 440 and stock heads. Went 11.96 for a best I believe but the 60' was a 1.49/1.52 3800 lb car. Cam and intake selection wasn't all that good back then and an 11 sec street car was tough to beat. L60 mickey tires and 3 inch exhaust. I'd launch on the primaries then stab the gas, or it wouldnt hook with the street tires back then

doesn't the pinion rotate up though on launch? with the shorter leaves on the bottom of the stack, as the axle rotates, isn't it pushing the shorter, bottom leaves up into the top main leaf? how would clamps help anything there as it's trying to twist the axle upward? that motion would be pressing the leaves together anyway.

I thought you wanted the leaves on the back section so that as the front rotates upward, it helps to prevent the leaves from separating from each other?
