On my 1971 climber it has both ARCTIC an CAT on it,I have acouple seats that I've bought and they only say ARCTIC on them.Like it was mentioned by 66178 rat-that would make sense,no tail light both words:shrug: I was talking to a guy who restores old Arctic Cat snowmobiles,he said they used what ever came in for shipment when building them,maybe this is true on the seat also:shrug:
