Exchanged the hyfaxs already 2012 kit ,due to the old ski handleing had to lean to one side frequently ,my balance is more to the right ,so that hyfax wore more ,I dont have a fancy skid lift so just put I lag bolts up through my shop ceiling into the truss than just used tie down straps hook to the grab bar to raise track up ,rolled track till hyfax can be seen through window ,take out the small #2 screw countersunk at tip of hyfax (driver end ),also remove anti stab tips off rails ,can use a block of wood or hard plastic to hit hyfax backward ,might have to loosen track alittle ,only takes twenty minutes round trip to take off and install ,next season Ill in stall new .
