City: Camarillo State: California Price: $150 USD For sale is a straight axle out of a 1948 through 1952 F1 pick up truck. comes with Both spindles and for another $40 a brand new king pin and bushing set. The spring pads are 29 inches apart and take a 1 3/4” leaf spring. The same spring in that Speedway uses in their gasser axle kits. I was going to use this for a project but decided to go a different direction.
