1966 rolling chassis, Box is in real nice shape, has tailgate, wood flooring is MIA, rearend seems tight, non-posi, no-title yet. $1000 OBO.
Also 1966 GMC long fleet, 1/2 ton, complete truck, aluminum wheels, pretty nice cab, box is okay but found some putty in the passenger side bedside, fenders have rust in normal spot, St. 6 engine, 3 spd overdrive [missing some of the equipment like the cable or whatever that shifts it into OD], runs and drives good, only thing wrong is that they used Chevy heater control cables so they're too long. with title $1000 OBO
I was or am going to combine the two if no takers

Update:
If you don't wanna use the 66 GMC for the cab/front clip, drivetrain ect. I've got a 66 Chevy longfleet 1/2 ton with the 250? Straight 6, 4spd. on the floor, it has the custom appearance pkg., coil sprung rear with 3.73 gears, non-posi, runs/drives good, lowered, nice ralley wheels with 275x60x15 BFG radials, Body has a few dings but it has very little rust. $1200 OBO
