This has a dump bed. It’s listed as a 1956, but that seems unlikely since none were produced that year.

“1956 Willys jeep fc170 runs and drives. dump works. needs some work. make and offer. good title.”
Fiberglass fender extensions and large cooling tunnel say late 1958 or newer. It currently has a $5200 pending sale.
