I never did get pics of it being used, I got rid of it because I got tired of removing it everytime I loaded my sidexside. Mine came from the factory with it installed, so I dont know what you would need to retrofit one to yours. I do know there are a bunch of floor brackets that mount to the ramp floor to hold the enclosure that I wont remove from mine since I would be left with holes.
Also I think the upper cable brackets are welded to the frame, that hold the door level. You can see the ramp which looks identical to mine in the below link. Let me know if I need to get more detailed pics from mine.
