I have a brand new rfrom polaris never been installed bulkhead and tunnel assembly. Will fit most i think, but i ordered it for an 04. I bought this two years ago thinking i would overhaul my pro x. Decided to update my chassis. I paid almost 1300 $ for this, looking for 500$ back, Huge loss but a cheap tunnel and bulkhead if your looking to go throuhg yours, or start a mountain sled...
