“This 1961 Willys Jeep FC-150 has been refinished in green and yellow and features a front winch, dual side mirrors, and a drop-down tailgate. The truck is powered by a 134ci Hurricane inline-four linked to a three-speed manual transmission and a dual-range transfer case. Further details include a side-mounted spare tire, a cab heater, locking front hubs, and vinyl seating surfaces that match the exterior color scheme. It was acquired by the seller in 2018, and subsequent work included performing fluid services and replacing ignition components. This FC-150 is now offered with a bed cover and transferrable New York registration in the seller’s name.”
