I see that there is a third seat for 2006 bearcat...no such luch finding one for 2005. Are they quite different? Can one from a 2006 be made to fit a 2005 without making too many modifications? If anyone has pictures I would appreciate it.
The speedrack system uses a small square peg (1/2 inch or so) on the seat and a matching one on the rack. Fabricating something to make it match shouldn't be an issue. But remember, you also have to move the the threaded holes that your rear seat fastens to now, back to match the new position. I can take photo's of the speed rack system, if you like but I sold my '04 which had the same setup as yours. Another option is, I see your location is NL. I'm on the west coast if you want to have a look.
