If it's a factory BB shortbed it's kinda rare. look for the high hump, remote PS resevoir, BB motor stands, 4 row radiator etc.
Does it have the SPID on the glovebox door? Check the VIN on the door post, should tell ya if it was a v-8, 1/2-3/4 ton. Check the numbers on the frame rail on the drivers side next to the motor, also think it should have the fatter drive shaft.
Check the body mounts at the frame for rust damage. Also check the rear end for a 12 bolt or Dana 60 (3/4 ton).
Beat em down on the price..good luck!
