What size?

[COX99]

I will be putting some 4.10 gears in my 99 Cobra. Where can I find the information of the size of the rear housing, and number of spines... things like this. Also where should I buy the gears? Thanks for your time!

The rear is a 8.8 and it has 28 spline axles and I would get the Ford racing gears. But you will have to shop around on the price.

Thank you for the info!

If you run into any issues trying to find someone to buy a set of FOMOCO 4.10s from, send me a PM. I have a guy in Ford Parts and I am willing to help out a Cobra owner overseas.

Thank you, I was thinking about the gears later on, I will be returning to the states...(someday) and Then I will install the 4.10s. With the Autobahun and the gas prices, I will need the higher speed. Thank you for the help!
