I know this is mainly a Chevy site, but surely there have got to be some Ford gurus here right?!?!?

I bought a used 9" and I'm finding it impossible to buy axle and brake parts locally without the knowledge of what vehicle it came out of. What I do know is:

28 spline
3.25:1 gear ratio
Limited slip differential
Big bearing
Date code is November 1971
Housing measures 60.75 inches from outside of axle flange to outside of axle flange.

Can anyone help?

I've tried following all of the 9" lists and it seems like a 71 mustang is the best bet but from what I've seen those were all small bearing.
