I used inner replacements from Chevy Duty and they worked great. The passenger side one we took all the way out and the drivers side we cut up under the location of the arm for the air conditioning (really the AIR VENT)amd patched it in. Worked out good, helps to do the inners they replace the outers. Does take a lot of time to get the patch in without warping it if you cut around the arm slot.
