Crash damage at passenger firewall? '63 C10

[lilpoindexter]

Hello Everybody:
It looks like my truck was crashed at some point, on the passenger fender, above the bumper, and the inner fender pushed in, on the firewall. The gutter above the firewall is about 1.25" tall on the driver side, but it caves in on the passenger side...plus my inner fender is spaced to firewall with a gang of washers.
My thought was to remove the inner fender, and fashion a mount that picks up on the two inner fender mount holes from the inside, and use a slide hammer, to try to pull the firewall back into position.
Just looking for peoples opinion on this carnage, and perhaps how you might approach it.
