I found the code on the axle tube
Its ZH which means its either a 1965 or a 1968 3;55 Nodular Iron 4 pinion design
Is there anyway to tell the difference from a 1965 and a 1968 rear?
are the overall dimensions the same or different on both years?

65 is narrower, but for an even easier ID look at the spring perch. 66 and earlier had a flat surface, spring was bolted on with a retainer. 67 and later used an inverted pocket to locate the spring (no bolt)
