Weld in subframe connectors for 76 Duster

2x3 box steel 1/8" thick is what i used. I layed it on its side and slotted the rear foot wells, and slipped em in. They stick up thru the foot wells 1/2" easily hideable with carpet. Also made my own front and rear torque boxes out of 1/8" plate sheet steel, and overlapped the rear ones over the top of my subframe connectors.

See my avatar pic and project pics for details lol.
