“Changing focus. I’m selling my FC-150 to make room for a different project. Truck does run. But I had plans to swap in a modern motor and transmission. Body has been separated from the frame and some body work has been started. Has some rust in the cab corners and under the battery tray. But overall it’s pretty solid.”
It has overdrive installed.
