Matt,
Looks like a pretty solid truck from the photo. The hard parts to find for that truck look to be mostly there -- the sheetmetal, bumper and grille. Stuff like brakes and other mechanical bits are available here in the States. Check out our LInks page and the Swap Meet and you can pretty quickly get a feel for what's available. Plus, most of us have not had too much problem finding mechanical parts for the Big Bolts from our NAPA chain of parts stores.
If you decide to get the truck, your fellow 'Bolters here will be able to help you find stuff, I'm sure.
Regards,
John
