I'd think you would have to drag it out and check the cab over to see if it is worth removing from the chassis. If it isn't beat up or rusted out the bare cab might be worth as much or more than what the whole truck would bring scrap and you folks would still have the rest of it to haul for scrap.

The fenders look to be pretty well destroyed so they aren't worth anything.

On the cab, doors, dash and some smaller pieces it is what is good enough for someone to want to use them. Then are they worth your time to remove to sell or are you up to have someone show up and take stuff off the truck before it goes to scrap? If the cab is solid enough to use without replacing a huge part of it and you have lots of time and the equipment to lift it off without tearing it up you might unbolt the fenders and hood (looks rotted out in front) and throw them in the back and take what ever you need to to be able to lift it off and set it on a pallet or something and offer it up for sale locally. You won't get rich but a couple of hundred bucks for a few hours work is a couple hundred bucks. Then grandpa still has the rest to haul for scrap.
