Hi, Is there a rubber/nylon/plastic cushion type block located on the lift arm just above the tilt cyl.mounting bracket???? My lift clys. touch the fender/ main frame of skid steer when lift arms are fully retracted. lift arm/boom has holes provided...like a cushion should be there.My parts book does not illustrate anything.Ck'd with local dealer he can't find anything either. I'm thinking there should be a cushion block between the lift arm @ the tilt cly. area and the main chain case when lift arms are retracted. Thanks, quinq
