The Timbersled I have is used. Its a 2015 Mountain Horse St.
I noticed that some fit kits come with a plastic sleeve before the spacers go in. My fit kit did not have the plastic sleeves in the box but there were plastic sleeves already installed and my spacers wouldn't fit. This seemed to make sense because the instructions said I may have to drill it out. I started that process but then as I was tapping the spacers in, the sleeves came out the other side. They are almost the same diameter as the spacers that came in my kit so they would be paper thin if I kept drilling them out.
Were your spacers tight or did the fir in easily but without any play. Did you have to drill anything out?
