Brakes by application I believe should be 53 on for 3600. I believe they changed from Huck in 52. They used the HO52 axle through 72. You are lucky not to have the Huck brakes as the drums are NLA.

When you pull it apart to check on the oil leak look carefully at the seal surface of the hub. If there are pits in it or a groove worn in, you'll need to fix that in addition to the seal. There is a Speedy Sleeve available for just this purpose. SKF part number I can't find at the moment so that means I'll need it again soon. It's available from NAPA and no doubt others. About $60.
