I have a 52 1 ton dually with the original 18" wheels. I found a 69 Chevy 1 ton dually with 19.5 one piece tubeless wheels and they have the same center diameter and same size lug holes as the 52's 18" wheels and even have the same flat lugs with the slits on both trucks. These 19.5 wheels do not have clamping plates and should not have them because they are basically hub and lug centric, correct? Are these style 19.5 wheels difficult to find? I was planning on trying to find an extra 1 or 2 for spares but have not seen any more of these anywhere. Just thought I would ask a few questions since most of the knowledgeable 1 ton guys seem to be posting on this thread, thanks.
I quoted myself because I wanted to update as I answered one of my own questions. I couldn't believe it but I found another single tubeless 19.5 wheel at a salvage!
It is identical to the 6 that were on the 69 1 ton so now I have a spare! I am not sure what these would have came on originally because my 69 said on the glovebox sticker that it originally had 18" wheels and tires. I know 73up duallys had 9/16 studs so these wheels would have to have been made 72 and earlier because they just fit on the 1/2" studs perfectly. I will keep an eye out for more but I have a feeling they are a relatively rare wheel.
