As long as you use the underlays from a 2003 or 2004 model it will be interchangeable from the High back to the Parks overlays. Things were different in 2002 and before, however, as they changed some of the dimensions starting in 2003. If you're gonna get new overlays anyway, might as well give the Parks a shot. It should work fine. I interchange them all the time. Note: The changes HL made in 2003 seriously increase the
ain-in-the-@ss">pain-in-the-@ss factor when rebuilding your bindings, so be patient, and don't strip out the slots of your screw heads with too much juice on the power driver. Have fun.
