Kimpex Anti-ratchet Drivers

Has anyone installed the Kimpex anti ratchet drivers in an "s" chassis Ski Doo? I installed them on my 99 670 h.o. and noticed the "teeth" on the drivers are hitting the rails. I noticed there are three mounting hole locations for the front of the rear suspension. If I drill out and move to the rear mounting hole will this remedy the problem? Any suggestions?

We have seen that a lot not just with the drivers you have but just about any make, I wouldn't move the suspension, we take the suspension out and cut the rails back for clearance of the driver and reinstall the end pieces. -- Bill

Thanks Bill. How much are you cutting the rails back? Will 1/2" be enough?
