B Body Drivers Side Crossmember Section

howdy people, cosgig here. I’m working on changing the drivers side floorpan in a 70 Roadrunner, and the crossmember is a little weak where it meets the rocker. I’m looking for about a foot of the crossmember end to weld into place, maybe up to the torsion bar socket. If anybody is parting out a 68-70 B body and has this section, please message with what you have. I know AMD makes the entire crossmember, but it’s $400, a little steep for just needing the end. Any leads or input would be much appreciated. I put a wanted on FBBO as well, but you guys have always come through for folks here.
