Hey guys, I have a 99 trx250. Just bought a warn setup off a local ad for a rubicon. It mounted up super easy. Just drilled new holes on the mounting plate. Took 20mins to mount up and works good so far. Just need snow now.
This pic is using stock rubicon holes. I moved the plate back a few inches drilled new ones so the mount doesn't hit my big tires and better weight distribution.
Hope this helps a little. I just google the hell out of it till I found a mount that looked easy to modify. To be honest almost any of the flat plate mounts will work fine.
