Changing axle from equal length to unequal

[mjshotgun]

I what to remove the equal shaft set up to unequal, my question is its a 88 Shelby Daytona A555 i what to get one from a junkyard without pulling mine out till i get time and what to know what years had the same spline set up, and if an automatic trans axle would work? i have read that people have done this swap without any problems. Any other input would be welcome.
Thanks Matt

yup, it will be same as NA A/T

the NA cars didnt get the equal length setup
