56 GMC panel guru's?

[jamieg]

I have been shopping around for a new project and i came across a 56 panel that my brother in law has. It was laying in some pretty deep muck when we rescued it about 15 years ago, and i forgot all about it until now. There is a fair amount of rust on it but i am wondering how hard patch panels are to find for it.

Also on the drivers side outer roof panel has a hole in it and am worried about the front pillars. I see the passenger side is rusted through. I am not too concerned with the amount of work involved in patching the rust on the lower part of the truck, as i am getting a project to hopefully get the family involved with (except the wife she likes to cruise but hates getting dirty). Does anyone have any advise for rust repair on pillars and roof, or if its even feasible to do it?

I have not tried to dig up parts for this year of truck so i'm just testing the waters.

Oh and here's the pics
