65705K27 is the part number to a pair of brushes at Mcmaster that need to be shortened to .500" long to fit the water pump motor. Otherwise they fit perfectly. Carbon files and shapes very nicely. These are only $11.66 for a pair compared to $52-$70 for a factory pair from the vendors listed in this folder.
