There are numerous aftermarket sources for any size wheel with whatever back space and bolt pattern you need. Wheelsmith,
Vintique, and Speedway to name a few. Aftermarket wheels will fit just about all disc brake conversions.
Trying to look for a stock wheel for a conversion can be time consuming, frustrating, and possibly more expensive than just buying them new.
