Not to resurrect a dead thread, but are there any 17" wheels with the 8 on 6.5 pattern out there that you have used? I found some on Summit and Jegs, but they have large backspacing that may not work. I have a 1955 first series 3600 that came with 17" originally, but all I can find are the 16.5 and 17.5" trailer wheels.
