If this was a army unit then the truck was probably prepped for scrap. I am thinking this unit was probably sold as scrap and probably was described on origianl manifest as such when liquidated by the gov't. This unit was more than likely bought by a person at an army base auction and sold to another then came up for auction at a civilian sale. You might get lucky and get by with just a converter. But with unit drained of all fluids i am betting it was originally sold as scrap.
