This is what it looks like. Personally I am going to one of these when I get another snowmobile or have to change a track on one of the two I own now. Tired of sitting on concrete floors with a stud drill installing studs for 2-3 hours. For an Ice Attack to fit on yours you will need to get an extension from 133.5" to 136" as they don't come in the 133.5" size. Those extension kits are found in the catalog link below and are not expensive and very easy to put. Tbh I would do it in a heartbeat vs as I said installing studs again.

This place is the cheapest I have found for it so far at $655 plus $20-30 in shipping.
Good luck and lemme know if you need anymore help.
