I'm running a 05 420D it and am trying to find a good spot or place to get new stab pads. My local Cat dealer wants $280 for one pad. Other parts vendors say that they cant get aftermarket ones. I dont belive that they dont exisit. The cat p/n is 2379356 they are about 8.5" wide and 18" long and are made up of strips of cut rubber. Maybe $280 isnt a bad price but it seems high to me!!!! Any pointers or advice?
