What year is your truck? The parts truck? What was damaged in the wreck? $350 sounds like a fair price, but I'd want to hear it run before I committed. I like to get my stuff REALLY cheap, and here in the NW Luv's are much more plentiful than where you are. Engine rebuild kits can be had for less than $350, but you still have machine work to do, etc. There are certain items that would sell here or on ebay pretty quickly, but not any one item that will bring you a lot of money. Ignition switches, sun visors, front valences (some years are harder to find), heater control valves, etc. Stuff like that you could sell off to recover some of your initial layout. Take a look at the classifieds here and see what people are looking for, might help to decide if you want a whole truck laying around, or if a rebuild kit would be better.
I'm rambling a bit, sorry. Good luck whatever you decide. I'm probably going to be looking for some stuff for my '75 soon...
