As long as the track is 2.52 pitch, it will fit a Stock Attak like yours. But be warned, many Ski Doo's have 2.86 pitch driver/track combos.
But you said you are getting new drivers? The two aftermarket companies that make drivers are Wahls and Avids. They both make perfectly good drivers IMHO. Just be certain you get the same pitch drivers and track, whatever you decide. Stock Yammi's came with 2.52 pitch drivers, and for ease of reference I'd stick with 2.52 pitch. But you could switch to 2.86 and it would fit if you switched both your track and drivers 2.86 pitch. I wouldn't do it, but you could.
Also, the Attaks came stock with a 9 tooth driver set up. Personally, I'd stick with 9 tooth drivers going forward (larger drivers assist to prevent track stabbing isssues and spin the track more efficiently).
But a caveat would be if you have some reason to drop to 8 tooth drivers, such as you want to run a paddle track and need more clearance than 9 tooth drivers offer, you might switch to 8 tooth. Just depends on what your application will be, i.e., how you ride and what conditions.
Hope this helps. let me know if you need clarification on anything.
