Crushed Door Post/Pillar

[ecriez]

I have a 73 Stepside and my daughter side-swiped a mailbox monolith, tearing out the passenger side of the truck. I easily replaced the front and rear fenders, but the door post is really a mess. The striker does not align with the door any longer (replaced door too). From about 12" above the striker to the level of the rocker panel, the pillar is a crumpled mess.

I cut out the bad metal, but am having trouble finding any panels to use to reconstruct this.

Any leads on this would be greatly appreciated.

Thanks
