Cast iron rear question

[Dntalman]

Do they ever put the cast iron housing in a automatic Mustang GT? My car came equipped with the 3.55 gear set. I was thinking that it may have the cast iron housing since it has the 3.55 gear set up.

I am almost 100% sure only the automatics don't have it. And gear ratio has no bearing on the material. I have seen them in 3.15, 3.33, and 3.55.

I just picked up an aluminum auto case for the weight savings.

Autos dont have a cast iron diff, only manuals. Ask Kelly at bmr how he broke his. Infact he has a thread on it
