I have purchased a 163 Polaris track that I am putting under my stock 156 02 800 edge. I am wondering what parts are needed to do so. I have figured I need new drivers to get the 3.0 pitch of the new track and also 7 tooth to fit the 2.4 lugs, rail extensions, and wheels? Is there anything I am missing that is needed? Also If you have more specs on the shaft size for the drivers that'd be awesome!
