The HPP-19190 is the internal part number we use for our Powerglide endplay shim kit for use with pump to drum needle bearing thrust washers. (kit includes one each 0.010", 0.016", 0.020" & 0.025" thick shims)
Tech Note: If you need to use this kit with a standard OEM style pump to high gear thrust washer, you will need to cut a flap spot to account for the anti-rotation tab on the OEM style thrust washer.
