Need help locating a part

[coyn]

I"m in the middle of replacing all my cab supports in my '66. I have ordered and received all except one section. Does anyone know where I would be able to locate the center section of the rear support? I have the outboard pieces from LMC but haven't been able to locate the center. I tried bending some steel to make a patch panel for the rusted out section but that didn't go as planned since I don't have a brake.

Any help is appreciated.
