Heaven help you..I know it is probably hard to find qualified techs that work on stangs but you are really rolling the dice with this install.

 

Are you going to install the gears yourself? If so and you need ask what pinion depth and backlash you're in big trouble.

Here is an article that should help you

I did my own gears having never don it before & had perfect results using the article below. I assumes that you have a good setup from the factory to begin with & you are using Ford gears for the rebould. Basically you measure your old pinion head thickness then measure the shim behind it, add them together, measure your new pinion head thickness then subtract from your total reached before and you have your shim thickness that should give you the proper depth. Anyway read the article & it works, I have the quietest 3.73's in town.
