riser bushings

[Tech7]

Hi, just registered on this site I am building a hardtail 79 XS 650, and wondering if anyone knows of any poly riser bushings to replace the rubber ones. They will need a center hole of 1/2 inch to take my aftermarket risers. I know I can spin some up on the lathe, but if someone already makes them, I'd save the hassle. Thanks.

Welcome! Can't help with the bushings but thought I'd say hello anyway.
