It's my understanding that the thicker CVs are from a '70-'71. For '72 Porsche went to the updated "lightweight" and thinner CVs.

I ran across this issue when I upgraded my '71 to a 915 trans recently.

I believe the axles are a different length as well?
You will notice there is a difference between the '71 axle flange and the '72 flange.



I just ran across this thread and thought a bump was in order.
