I have one. My bladder was good, and I had already ordered the bladder. It was on backorder, so I told my shop to go ahead and tear down the shock, if the bladder was good, to rebuild it and I'd just keep the bladder. PM me for pics. I can only text or email them. It's oem. BNIpackage. I had my shock done at G and R motorsports in Walton ky. The tech there used to be the man at Mototech in Latonia (near Covington) Ky. These guys are really good and reasonably priced. I'll sell u the bladder for whatever I paid plus shipping. Mine is for an 87 shock, but I'll call G n R to make sure it's the same PN.
