Boxing Stamped Upper Control Arm '65 2+2
 

I have looked at the TCP boxed lower arms and got a good idea of how that is done. I also understand that the upper stamped arm can be boxed and get substantial uincrease in strength and rigidity without paying the big bucks for the tubular units.

I am looking for information regarding where are the right areas to weld in the plate to accomplish this. Links, suggestions whatever are welcome.
