I checked the Tech Archive and there is some good info there, but not what I was looking for.. I am wondering what the factory count is on axles splines for 8 3/4's and Dana's. I have heard numbers like 29, 30, 31 and 35 but I am looking for something more factual and/or year specific. Thanks.

Most mid '70s and newer truck and van Dana 60 rears have 30 spline axles. A few late models use 35 spline, and many '60s-mid'70s use 16 spline.
