Replacing the cab presents it’s own challenges. You have a 1955 first series. Those cabs are rare as hens teeth. You can replace with an older cab but it will be a 2 piece windshield. You can cut the back half off of a donor cab 1947.2 thru 1955.1 and weld it on yours. Again, not for the unskilled fabricator. Technically you can build an entirely new truck with available aftermarket parts. It certainly can be saved but it won’t be easy.
