After a year spent on eBay searches (and purchases), joining countless special interest Facebook groups, and lurking on a plethora of other interweb sites, it finally all came together. And what a glorious sound it was.
So now it’s on to the frame. The first challenge will be to come up with a way that it can be straightened, or at least untwisted enough so it will get past a safety check (i.e close enough for government work). Eyeballing it it looks like the steering head is about 5 degrees off vertical, and it's a stamped steel frame, so I'm open to suggestions.
