55' Chevy Rear End Questions

[jy211]

Got a couple questions...

Who can make me or supply me a 12 bolt rear end for my 55' sedan? I have used Currie before on our 68' Camaro...I also know Moser probably can do this as well...Anyone else?

Here's what I am trying to accomplish with this...I am moving my factory leaf springs into my frame rails (I have 3" lowered leafs to replace the factory leafs).

Here's the kit I have : http://www.classicchevy.com/product....dept%5Fid=1821

I want to be able to do a nasty back spacing on the rear rim so this kit is giving me some extra room so I can tuck a 20x12 rim (with a 3" mni tub) in the back and I need to know what length rear end I can use. I will be using Wilwood rear disks in the back....gotta order those too

Thanks fellas
