Spotted this on eBay it's in Spokane Wa. and looks pretty decent. No motor, says it's an F3 but it has the 5 lug x8 wheels. Serial number matches F3, so I don't know if it's a cab swap or suspension swap. Guy has two more truck not listed.

Looks like the running boards have been cut off at back of cab. Strange that the Wipers are on top of windshield as well.
