Hey guys, my 66 250 has the double groove water pump pulley but only has one groove on the crank pulley. Does anyone make a pulley that mounts on front of the crank balancer that adds a second groove or do I need to look into pulling the single groove balancer that is on it and replacing it with a double groove balancer?
