Hello, I have a 2008 Apex MTX SE 163 and after 715 miles the sliders are worn to the wear line in a couple spots. I am looking to replace them, but cannot seem to find the same length slides anywhere. The ones on the sled now measure approx 63" and every website I have found that has slides that would fit the profile are 56 7/8" long. Does anyone know anywhere that sells longer slides that will fit a 163" Apex MTX? Alternatively, will it hurt anything to install the shorter slides? Thanks!
