I have a good friend that used to work for these guys, and after thanksgiving break he brought back the catalog for me. I spent hours flipping through it, finding so many parts that the truck either needs, or would just be nice to have. New trim? Definitely. New heater fan and motor? Probably. New parking brake release lever, need that. New interior dome light? Yup. Bunch of patch panels? For sure.
It's seriously dangerous. My wallet will be unhappy with me. Fortunately, most of what I need were small cheap parts, but those add up quick.
