What I saw: Radius arms cobbled together with tractor links and what appeared to be old CAs that were bent to fit. CA mounts that were just tabs, not boxed in at all and they were actually pulled in together from tightening the bolt down with too short of mis-alignment spacers. Cold lapped welds on the CAs. Tractor links that were showing several inches of threads with no jam nuts.
The cross member was OK, IMO, but I would have liked to have seen a sleeve where it was bolted to the "C" channel on the unibody "frame".
Put the pics back up! This is a place for learning and criticism. You had the right intentions, just poor execution. If you really want to learn from your mistakes, start now.
