I just put one on my FST last night. I bought it late in the season last year. The Polaris seat was out of stock so they sent me the M-jack told me it was the same seat. I had to grind off the front of the mounting tracks a little to clear the gas tank mounting tabs, but other than that installation was straight forward. Be sure to leave enough clearance between your seat and the mounting brackets as the brackets stay on your sled. I have not sat on it yet but it looks comfortable and the seat slides on and off easily.
