Just trying to learn here, but are you saying a mig weld is only 80% as strong as 2 bolts or a arc weld? In my world this changes daily so I'm interested in your perspective. One year the standard is to glue bonds, next year they say rivet and glue, next year they say spot weld only, next year they say bolt every 3 inches and so on. Mig is 80% as strong as an arc weld from ASME section 9 1/8" steel is fine in the strength issue If you look at the US Car tool molded connectors that get welded to the floor pans they are only 20 gauge -199 bucks- As it does not take much to strengthen the bodies As for welding, borrow a rotisserie it will make your life better I built the the one shown

I used roll bar tubing 1 5/8 i think, flat plate, and a peice of angle. Works great. I put the angle iron on the front frame by the rear Torsion bar mount, ran the pipe straight to the rear, flattened the pipe with a torch bfh and a vise. Welded the pipe onto the rear frame about 6 inches, welded the plate vertical on the rear frame, then heated and bent around to the other side and welded the sides. I have a 73se with no vinyl top, the body filler cracks by the quarter windows, this slowed that down. It's a drag race car mostly. If I were to do another I'd do it the same. Super easy and cant be seen much. Paint it black and hardly noticable.

Welds look like a hogs a$$ sewn up with a log chain but it works. Pics sucks too. Second one is sideways.
