I have a V8 K-member and I'll soon have ready a A-body complete rear. I'm rebuilding the whole rear. new brakes ,cylinders,seals, bearings, new stainless steel brake lines,hose, etc. It is a 3.23 open and you can use it as a small 5 on 4, or axles have been redrilled for 5 on 4.5. I'm in Plant City Fl.
