hey dudes...i just recently but a 1980 K5. I'm kinda new at this, but love the hobby. The beast is in pretty good shap in regards to engine, tranny and transfer. But body wise needs a lot of work. One thing that has me especially worried are the doors and window mechanisms; the passenger side and rear window system are pretty much rusted and shot. Based on any of you guy's expierience, should I just look to buy doors from a junkyard or can these systems be restored? PS: I live in Costa Rica but you'd be surprised how many love good ol' American Trucks here. Junkyards are do-able.
