67 Dart Build Triangulated 4 link & Mini Tub

Fishy made a good point that I didn't notice from the pics. If it's the plate just notch it. I don't think a safety inspector would give you grief over that. I don't know how much experience you have doing roll cages and don't want to insult your intelligence with unwanted advice. I used to bend up custom cages from 20' sticks for a living and we TIG welded everything. The fit had to be real tight so it was a trim & fit, trim & fit ordeal every time.

I need to go back and check your pictures for a minute.
