other then finding a good rust free doner truck is there some where i can order patch pieces for the typical rust areas? ie, door seals area, windshield frame, etc?
That'll depend on the year you're hoping for. Rockauto.com has some of these, toyotafiberglass.com has some. You may check ebay, though that might be hit or miss
Best bet will probably be a donor. If anything go to a local bodyshop and ask if their parts suppliers carry anything and have them order for you.
