Hi all, have been having issue with the Polaris rubbers barely lasting at all. I purchased some of the Ski too rubbers from an 06 summit after reading those worked better, but I cannot for the life of me get these things to fit. Most guys said they just used a sled lift and a block of wood under the ski, but we couldn't get the bolt thru even with two guys. Is there a trick to using these? Do I need to trim them down a bit?
