I have an early 8-3/4, need info on

These rears were used in old tractors in the 50's and 60's . I recall seeing and old Panzer wide track row tractor with a widened one in it . The flanges on the housing end look the same. They used these in many different tractors. The chrysler rears had tapered axles these are splined like a tractor style. They were all 410's in the tractors. Also used in cleat trac style vehicles.. They take a GM joint.
