Thanks Clifton. I think I may have some solid axle hubs but I just gave away a bunch of wheels. Dang it! I may just have to go with some big washers for now to keep it in. I do have locking front skewers so maybe those w/ large washers will hold them in until I figure out how to mount it to the lowrider rack holes or finding a solid axle. Next time I order something from Niagara Cycles, I'll grab an axle.
