Mono to Multi Leaf Spring. HELP!!

Ok, heres the deal. I recently grenaded my 10 bolt rear end and rebuilt another. The new 10 bolt has mono leaf perches on it, but my car has multi leaf springs. I bought the mono to multi conversion kit from detroit speed (link below). Once I bolted it up, the rear end is able to slide on the leaf spring forward and back. There is a gap between the leaf spring and my bottom shock mount (in this case it is my slapper bar). My question is how can i get a good clamping force between the rear end and the leaf spring? Do I need to run a urethane pad under the spring? Everything else is ready to go and I'd sure like to drive my car again. Please help. Thanks

The Multi leaf setup should have a pin that will hold the rear in the correct position. I think it's 3/8".

These guys are incredible, we seen their work in person, and it is outstanding!!!

Click on the cars and you can see the builds and fab work.

The back end of my 66 bottoms out sometimes over RR tracks or other large bumps in the road.. Do ya think Multi leafs would cure that issue ?? I have air shocks on now but if I don't have enough air in them.. the back end will bottom out..

No it sounds like the multies you have are worn out, they may need to be re arched and banded.

back when I had my 66 I installed some wagon monoleafs and it rode alot better - was a stiffer spring and no mods needed

I switched my old 71 mono leaf out to mulitleafs and I had the original 8.2 mono rear end in it that I built. Didn't need any kit, all I had to do was drill the spring locator hole out bigger. Shouldn't be an issue going from mono to multi, but the other way from multi to mono, I could see how the rear end would be loose.
