“Very good condition 1953 Willys Jeep with hydraulic plow and heater. Runs and operates very well. Inside and outside very good condition especially for a nearly 70 year old vehicle that was well kept thru the years. Will make plowing snow easy, can pay for itself over time.”
Love that Steering Wheel “period correct modification”?
Seldom have ever seen around here,is a blade with the trip spring in a tube. Can use a compression spring then , should last quite a while
Looks nice.
