Hi guys im trying to decide exactly what front end and rear end I have. The front is a HD Dana 44 frontend and the stamped number on the tube is 610037 5 and then beside that number is a 15875. Then the Dana 60 rearend has 11 30 3A1 then beside that # is 60 32362. Any help would be great I need to get parts for both of these so I need to know what they are.
