Unbelievably RARE 1985 Ford Ranger 4x4 Diesel

I bought this truck a few years ago in Southeast Kansas. I have recently spent a great deal of money on the truck. It has a rust free bed out of Springfield. MO. I just installed a new 4d56 2. 5L crate engine from Maximum Overdrive in British Columbia. Canada. That engine alone was $5K not even counting customs fees getting it imported into the states. A month after putting the new engine in I was on my way home from work and it started losing oil pressure. 15 seconds later it shut off. I am pretty sure the engine is locked up. The oil pressure dropped amazingly fast. The truck has a new brakes front to rear. Another $1K was just spend on new wheels and tires. There has been a ton of money dropped into this truck in a very short amount of time. I am just burned out. 4x4 works well. It was getting 35 mpg before it stopped running. All parts are readily available on ebay. Please e-mail me with any questions. Thanks for looking and good luck bidding.
