Welcome to the site, that truck sure looks heavier than a 1 1/2 ton, quite a workhorse.
There are lots of places to get parts, although it's always easier to find parts for the light trucks. Check the "Links" at the top of the page or put an ad in the swap meet section. If you need help with the VIN, you need to post your VIN or go to "Tech Tips" and scroll down to VINbusters.
Good luck with it.
