Recently studded my Mach Z and installed the 1" tunnel protectors. While at the local SkiDoo parts department getting the protectors, I asked for the four 3/16" steel rivets you need to re-attach your snowflap at the conclusion of your tunnel protector fix. At over $2/rivet, even the Parts guy encouraged me to get them somewhere else. I took his suggestion, but haven't found a supplier of these rivets in Kalamazoo or on the internet. Any suggestions or do I just surrender and return to the dealership? It's not that much money, but snowflaps do get torn and lost especially when backing up your sled with a studded track.
