I have my grandfather's 1920 Buick K45 which has been in my family since new. It has 4 original Firestone Non Skids. While being on loan to a small museum, one of the Firestone Non Skids went flat and the spare, which is a poor regular Firestone was installed in place of the original. Apparently someone tried to remount the non skid to the rim without a rim tool unfortunately, and failed. Some considerable time went by before I received the car back. The split rim lock and valve stem cover was never recovered as well as the parts to mount the spare tire to the carriage. I do have the tire and the rim. The bead of the non skid was damaged some and one of the latch bolts threads were stripped too but that's a whole different story... Anyone have any idea where I can find the correct latch parts, see image, or perhaps a complete original style rim. Tire is 34 x 4.5, I believe the rim is 25 inches. I greatly appreciate any assistance or advice on finding the parts and or someone that can remount the tire and rim. Thanks
