Mild Donk job. At least it could be easily returned to stock. Has ubiquitous Oldsmobile 307 (5.0L) Will be very hard to get that kind of money, unless a Unicorn is found that simply wants that year and model. This is an eighties Wagon dumped at the Albuquerque U Pull It. Has the original wheels, and that Oldsmobile 307.
I would doubt it. The olds diesel experience was brief, a few years in late seventies to perhaps’82 or ‘83. Passenger car 5.7’s were used for the diesel conversions to best of my knowledge.
