exactly...I always saw 41 10 for the tooth count and thought they were all 4.10 gears in GM cars...although when I was a kid we always said 4.11 posi....I guess they changed from 4.11 to 4.10 after 66..????

and thanks for the responses....that is about what I thought the value was. It is ashame, because at first I was told it is an original KK 4.11 posi from a 69 Chevelle...I thought I had the holy grail...
