So an update on my imaginary dirt bike. Finally found a guy to weld the tank. I thought he would measure, cut and weld but he only had welding in mind. Tonight I cut up a perfectly good, $300 tank. I'll show pics later but it looks really good and it should fit like a charm. Need to get some polypropylene sheet to fill it and we're making progress again.
I sent an email to JFab last Feb about a head stay. He seems to have dropped off the planet. Anyone hear from him?
