I had to replace my lower right front pilar due to rust (Dah). My new piece does not have the support brace and nuts for the door hinge. The old one is welded on and will be destroyed if I try to grind it off.

What has others done to mount a hinge on a new lower pilar?
Can I just weld three new bolts to a piece of sheet metal and then weld that to the back of the pilar? Or do I need to build the braces like factory. I'm not sure if that was for support of the door or ease of assembly at the factory.

I can't find this bracket anywhere for sale.

Thanks
Rick
