1980 Datsun Pickup 720 King Cab

New Mexico vehicle. We purchased this truck from a seller in '05 who said this was a "snow bird" vehicle and it was parked and towed behind an RV a lot. The mileage was 56,249. The mileage is now 79,500 on the odometer. If you are serious and want confirmation as to if these are original miles or not, et me know what I can do to clarify this. The truck runs well. Cruises along at 80 mph nicely, o overheating.
The "front end was done in '08. This included upper/lower ball joints, uter tie rod, enter link, nd toe in. I've replaced the starter, olenoid, nd carburetor. I put a weber in because I got tired of trouble starting on cold days.
With any inquiries, lease know that I am not a mechanic and don't have much experience selling vehicles. I will do my best to answer your questions.
