hey guys, a couple weeks ago i found a website where i could order a kit with all the axle tabs i needed to weld onto a gm 12bolt axle that would bolt right into my 85 z. now im having major problems finding it again... any help?!

the problem is the torque arm, you will not find anything to mount it. It has to be fabbed from scratch and welded to the cast center section by a professional welder who know what he is doing and how to weld to cast iron.

as for tabs, you can just cut all the mounts off the stock rear and re-weld them, but you have to make sure everything is mounting in the exact same place and at the same angle of you will have problems.
