Okay I have both set ups.
The riva 3" front air was on my 08 X when I bought it and I upgraded to a 4" kanaflex. The only thing missing is the aluminum bracket. It wasnt on my ski when I took it off and I ran the ski like that for a whole season. Due to that being missing Ill sell it for $125 plus shipping.

The riva rear air has the silicone piece that goes onto the s/c and the plastic L shaped piece but the aluminum piece that bolts to the seat cowl is missing with the lil rubber flaps. I have no use for this. If someone does its yours. First $100 shipped gets it.
