MN Rear frame crossmember

[CabinCruiser]

City: Twin Cities

I'm looking for the rear crossmember that joins the frame rails right in front of the gas tank. I've just started my build and it's the only part of the frame that has rusted beyond repair. I have tried driven auto parts as well as bronco graveyard. TDK will sell me the crossmember, however, it doesn't have the angle plate that laps over the frame rails so it would really be no different than just buying the steel tube from a local supplier. I'm looking for the steel tube that laps on the top and bottom of both frame rails. Thanks!
