C30 - Dually Rear End & Wheels?

[Sick66c30]

I have a '66 c300 flatbed with 18" three piece wheels. somw people call them widowmakers lol my dad calls them 'spokes'...claims back in the day if you had 'spokes' people envied you. but anyway, It seems that the bolt pattern is the same all the way up to '87? but my studs are only 1/2 dia.??? I would like to keep the 18" size wheel but not sure how easy it gona be to find a one piece wheel that size with those studs. might even consider a 17'' wheel but to tme the 16's just look like go-cart wheels on my truck with the huge fender wells. thanks for any input. I love this forum!

You will just need the correct lug nuts for the wheels you choose. If for some reason they are not available with a 1/2-20 thread, then you will have to change all of the wheel studs.

All the more reason to upgrade to front disc brakes and a Dana 70 or a 14 bolt with higher gears.

you can get 1/2" lug nuts that are larger externally. I bought them from a local automotive jobber for my C30

I had the exact same issue with my 69. I had a set of wheels from a 92 3500
I ended up using 1" or 1.5" spacers, I don't remember which, front and rear.
One bonus, it gave the truck a wider stance, which looked great. I know some are scared of spacers, and I understand that, but I hauled a lot of weight on this ole farm truck with no issues.
