I think your best bet would be to go with a rearend out of a thirdgen f-body. Since you'll have to replace the entire rearend, now would be a good time to get a posi and possibly a higher gear ratio. The highest factory available gear ratio that came in 10 bolt thirdgen fbodies was 3.42. That was only available with the manual tranny. You'll have to get all the obvious stuff for the breaks, like you already mentioned, but also remember that you'll need to get a different proportioning valve to use disk brakes. I'm not sure about the emergency brake, but you might need to swap some parts for it too. I think there's a tech article about how to do this in the FAQ.
