17 or 18 rear wheel? WTB 18 rear hoop.

[kball]

I have a 78 750k with a 17" rear thats in decent shape, but I want to get the wheels powdercoated and relaced. Seems like there's way more tires and spoke kits available for 18s. All I really need is an 18in rear hoop thats decent enough to blast and powdercoat. I just dont see many guys posting stuff for sale or needed on this forum so I dont know if its cool to do so. Thanks

You can certainly ask. The forum is small with only this one section.
Aside from that, a 16 inch rim is also available. This is a harley sized rim and so a good number of tire choices is available as well as spoke kits.
