'65-'66 Rear Axle Interchange Question
I always thought that big-car rear axles were essentially the same from '65 to at least '70, but recently had someone tell me that a '66 axle is wider overall than a '65 axle. Doesn't sound right to me. Can anyone shed any light on this? Thanks!

Same. Check the other threads in archives. Entire assembly is identical '65-6. Axles will pull out and stick in to either one. '65-70 internals swap except for '69 GP.

FWIW: the pinion seal shows a different part number for the 65 and the 66 to 70. I've never compared the seals to see if there is a machining difference in the carriers or not...

The pinion seal started to leak some time later and my diff guy was having difficulty getting a seal. I would assume he was looking for a '66 seal and I never told him it was a '65 diff. He eventually solved the problem but its something to keep in mind for the future. Thanks Ian

Rock Auto calls for SKF 19310 for '65 and SKF 19273 for '66. They are definitely different. Here are the specs:
