I decided to make my own 2x3 x 1/8" subframe connectors for my '72 Dart Swinger after reading this article: https://www.bigblockdart.com/techpages/connectors.shtml

Unfortunately I am going to have to notch the rear footwells (and then to weld the floor pan to the connectors, remove the seats and carpeting). The car in the pictures cleared the box tubing but there is no way mine is going to. Oh well, such are body tolerances (especially since some of the floor was replaced by a previous owner, ditto the spring relocation).

However, the left torsion bar crossmember has a "bump" in the rear-facing side. Looks like it was made that way, not bent in an accident.
But now the 2x6 plate on the end of the connector won't sit flat against the crossmember.

Should I hammer it flat? Cut it out? Or notch the end of my connector so the crossmember doesn't require massaging?
