1969 Dodge Dart GT freshen up

Old one is probably OK just check it for straightness across the rotors and the pump cover and check the clearance between the rotors and housing. Check the gears for galling, etc. While it's apart you can clean up the passages for better flow, kinda like a gasket match. Once you have it apart, you will see where you can smooth it out. Just make sure you clean out the metal chips good!
