Didn't mean to cut you out. We're just talking. If you're really into it, I'll step asside. I've got enough projects for quite a while. I do want a C7/71/72 and a C9/91, but can take care of that later. Get it from him for $25 plus shipping (what he'd mentioned). I may be able to help you out with parts needed for it. I don't have any more spare fuel tanks, so you'd have to either save the one that's on it (looks pretty corroded) or find one elsewhere.
I can still help him out with his XL-12 parts needs, regardless of whether or not you or I get the C-7.
