The engine, assuming it was NOT swapped out, should be a 1987 production engine, manufactured under a contract awarded in 1986, so dont let the 1986 scare you.. Mine is a 1988, and has the same contract date.
Other plusses..
It has the -1D block with a D model turbo.
USAF is SUPER ANAL about maintaince, so every oil change, wheel bearing repacking, and anything else it needed according to the TM was proabbly done.
The split brake system is a HUGE saftey plus
Rustproofing (look for a sticker saying so in the glove box, and under the yellow dataplate on the drivers side of the cargo bed)
It's a dropside.
The USAF swaps out trucks every 18 or so years, so thats probably why this one went to auction.
It has all the sideboards, bows and canvas..
Hardtop that doesnt look bashed in..
Looks to me if you get a passenger seat, 2 headlights, fuel guauge, and the door cover, thats all the missing parts you can see from the picture.
If you do decide to keep the truck, I'll throw in my passenger seat that matches your drivers seat and the door cover. You pay shipping.
