I have his LCAs in my KOS Demon to allow me more room where the torsion bars were. I do not have the brace for the pivot pin cause I don't I need it. He made me a couple pins that work with the stock K-frame, and you weld a brace "washer" where the pins usually waller out the K frame. Care must be taken to get that doubler welded in the right place to keep the LCAs aligned properly.

I think I have 400 or 450# 8" springs on the DA Viking shocks.
