The ebay listing seems to be for the rollbar only. The ROPS kit, which is still available new from JD for about $400, includes all the mounting hardware, spacers and studs for the fenders, and a seatbelt assembly. Also, the ROPS for the 850 and 950 are different, according to jdparts.com. I bought a kit from JD when I got my 850 about six years ago (the kit was only $360 then) and it took a Saturday afternoon to put it on. JD has always has a company philosophy that they sell ROPS kits at cost, so it'll be the most cost effective purchase you ever make from JD.
