it won't sell at that price, "totally original" only means something if it's in very good condition, and that trucks had a hard life - the wiring will be shot, all the driveline bearings will need replacing, looks like the windshields are fogged beyond use, upholstery will be brittle at best and a total repaint means total disassembly - it'll need thousands of dollars and a lot of time to make it a truck yer grandad would be proud to drive
give the guy your number, tell him to give you a call when he settles on a realistic price
