I picked up a used set of Mohawk Skis. SLP"S Website only list saddles up to 2012 for Yamaha Japan built 4 Strokes. I ordered those saddles. Called SLP. They said won't fit. But the 2012 Apex has the same spindles as my 2016 Vector. Anybody have experience mounting these. I have over 2 feet of snow on the ground at my house. Trails have not been groomed. Need to put away deck furniture etc. Hoping to mount these to reduce getting stuck. Thanks for looking.
