So, I picked up this seat a few days ago. Apparantly for a CB500K, but I thought, well, it just might fit my '76 CB550F (wishful thinking). It's close, but not quite.
I might be able to cut the seat pan at the front to shorten that part, and the holes for the hinge and latch look like they'll line up. However, this will require some precision work, as I would want to preserve the current upholstery on the seat. If I'm going to recover it, I might as well build a whole new seat.
Thoughts? Anyone ever seen/used one of these before? If I can't make it work easily, I'll be selling it. So, if anyone's interested, let me know. For some $ and a good condition CB550F seatpan (don't care about the foam or vinyl) I'd probably let it go now.
