I found a 2000ish 16" dually wheel today and it measures right around 13.75 or a little more so it may just fit the 61/64 rears since that is about what they measure. I can guarantee there is no 16" wheels that will fit the rear of my 52 like BarryGMC said they would and do on his 50 in the parts wanted link I posted above. The rear drums on the 52 measure right at 14.75" outside diameter on the front of the brake drum. I have a set of GM 17.5" wheels and they will not even fit on the inside rear and they measure almost 14.5" inside diameter across at the rivets. They still would not clear even if the rivets were not there as the back of the wheel hit before even contacting the rivets. I am going to find a factory up to 2010 17" dually wheel and do some measuring. It would be a good deal if these would clear on 52 just so others might be able to use them on their early 1 ton duallys when not wanting to use the original 18" or 19.5's. If they measure 1" wider inside diameter than the 2000+ 16" wheel I have, they just might work on the early(40's-50's) DRW rear drums.
