I'd seen the hubs for sale (though not that specific page; thanks!), but really what I was dreaming of was a preassembled, swap'n'go assembly that didn't require buying a number of different components, rebuilding bearings, etc. I'm working on a gremlin restoration that demands nearly all of my time, so while I'm willing to do maintenance work on the eagle (my daily driver), the time to do the front wheels on the eagle is a bit more of an investment with more downtime than I prefer. I doubt I'll find them to be a direct replacement, but boy, wouldn't it be nice?
