HD OEM backrest for sale, it fits Harley 4-point docking hardware. Metals are in great condition. I'm only asking $50 plus shipping, because if you look at the last 2 pics, you will see a small triangular piece of plastic is missing from one of the release latches. A pair of new latches on eBay runs about $15. So if you're looking for a backrest cheap and don't mind the extra effort, now's your chance.
I'll calculate shipping based on your zip code, so include that in your PM if you are interested.
