I just came across your wheel post and I think I'm to late for these wheels but if you should find another set I am looking for six. My name is Jim Jatho and I live in Augusta, GA I recently found a '48 F5 flatbed dump that I am restoring for use around our farm and maybe parades with the kids. I have ten wheels but 8 are "widow makers" and two have split ring that I would rather not use. I am new to the forum and can't believe all the information I have already found. What a great site. BTW if anyone can tell me how the mechanical dump cyclinder is put together I would appreciate it.
