Yup JC wheels are really your only option if you direct fit wheels that are readily available.
I run B2/B3 CVDs & wheels but even those wheels are not that easy to come by now (although I believe there is an avaliable alternative from the Thunder Tiger RTR B3 clone?)
I do actually have a pair of B2/B3 sport wheels which have the part-tapered holes & are a direct fit onto the older ali tubbed cars
