I Have a even more Rare Cat Endura R4010. The model with the Fiberglass
European Body work. I think it was a Factory Huskavarna Pitt bike ? It is gelcoated blue with factory race logo's. I don't think i'll ever be able to document that but it's to nice to be a Home job. Yes the jackshaft bearings do bolt onto the frame. I'll put some photo's in my galley soon.Good luck !
