Subframe connectors for a driver/cruiser, necessary to weld to floor?
Too late.
I just got done doing 2x3 tubing sub-frame connectors on my '73. Slotted the floor and welded them solid. Well, I slotted the floor but in the interest of time I had a buddy weld them solid. He did it all in about 4 hours (sub-frames connectors and front/rear torque boxes) while it would have taken me 24 hours to get it done.
I debated about how I wanted to do them for some time, but in the end I liked the idea of the diaphragm action the floor would give them so I decided to do it the hard way. With no definitive testing to say one way or the other, it was the way I felt best about doing them.
I basically copied @moparmat2000, except I didn't slot the rear sheet metal where there were multiple pieces coming together. I do have some work to do there to finish things on top, but that can come later.
