Opinions on (probable) GMC market value

[Coley]

Ok guys....how about some opinions on possible or probable value? (...who doesn't like that 'ask'...lol)
The truck is '67 GMC 1/2 ton (small back window/sloped hood) LWB model.
It has a 6 cyl (250) and has been converted to a 5 speed manual and has 3.73 posi rear.
Some rust in the lower regions but not a complete wipe out body/condition wise. The truck is still pretty stock and original but it needs a resto OR it could be used a relatively good, economical daily driver....perhaps a candidate for shortening/lowering?
Pretty much everything in the truck appears to work except the original windshield washer (no surprise) and the signal lights (flasher unit?).
Runs great, shifts great, good brakes, good tires, very solid frame....wood in the box needs replacing but it is more or less there.
Other points: rear step bumper, trailing arm suspension (not leafs), c/w the original radio (not installed), original air cleaner (not shown installed), seat needs recovering, includes in bed spare tire bracket, non-original mirrors.
Ok guys....have at 'er and weigh in, I'd love to get some value opinions on this.
Many Thanks
Coley
