now stock 99+ axles have the following measure:

diag: 30 11/16"

axle shaft length: ???

I needed axles with 2" shorter axle shafts, not diagonally like Moser likes to measure. I know a^2 + b^2 = c^2 but Im getting the hub RADIUS of 8.13". Its a right triangle with the longside being 28 11/16", the bottom as 27.5" and that makes the radius 8.13" unless Im doing my math incorrect.

I told the guy on the phone when ordering axles I narrowed the rear 4", 2" on each side. I needed axles with 2" shorter axle length, not diagonal length....apparently he did not understand. Apparently NO ONE understands up at moser when you modify a rear end and cut out the length from the housing you are altering the axle shaft length thats its not the same as taking out 2" of the diagonal length.

I need the diagonal length of a stock 99" mustang 8.8 axle that has been shortened 2" in the axle length, not diagonal length. They stand by their product saying that they are correct...I dont understand how they come up with their math.

in a 3,4,5 triangle the math works like this... 3^2 + 4^2 = 5^2 which equals 9+16=25.... now with their math they say 3^2 + 3.5 ^2 = 4.5^2... 9 + 12.25 does not equal 20.25... that 2nd equation would be me saying I took out .5" of the bottom side and their math says it equals .5" out of the long side. They are 1 full inch off on their measurement....

Can anyone help?
