Hello Ross, thanks for reaching out. We do carry the 3/4" ID bearings part # TMK36FR, but I am sorry to say we do not offer a hub for a 3/4" straight spindle. That spindle size is now obsolete, and I am not aware of any hubs made in that size. Unless you can find something used/secondhand, parts for that may be impossible to find.

In this case the next step would be to look at replacing the spindles, or replacing the axle entirely with something more modern.
