I have a very clean used BMW Seat, from a 1980 BMW R65. The seat has been disassembled, pan de-rusted and re-painted, and reassembled with stainless steel rivets & threaded fasteners. There are couple of small flaws: a few tiny holes on top right rear, and a small tear on bottom right and bottom left. Both tears have been re-enforced with industrial tape, from behind the original vinyl upholstery.
I'll take $150 including shipping, within the 48 contiguous US states. You can pay me via PayPal friends & family (no fees), or Apple Pay. If interested, please send me an email: rockyhayes AT gmail DOT com.
