I'm pretty interested in your RV cab and how you fix it, hoping to see you use the patch panels you bought, I have a 67 project waiting in the wings that has a pretty rusted out cab, all that is left that's good is the back wall and glass. I found a 67 RV cab for it with the same walk thru cutout, when the time comes i'm planning on doing the same type of repair. Of course i'd like to see somebody do this before i ever attempt it myself.
Welcome to the board too.
