Cab patch panels

[Nick_R_23]

This is on a 65 C10. My cab has the standard rot and then some. Definitely needs floor patches, inner and outer rockers, cab corners, etc. No big deal, standard stuff for these trucks. My problem is that the lower door hinges are completely rotted away and the rust gets pretty far up in the cowl, probably more than most trucks would see. I’m struggling to find patches for these areas. The only thing I could come up with are these side panels for the cab, but at $1500/pair PLUS still needing all the lower panels, I can’t justify that kind of money. Is there a lower cost alternative to these? Finding another cab likely isn’t an option where I live.
