I will probably have somone set the rear up for me, I have successfuly replaced a posi diff in a 9.25 chrysler however this rear is going to have a bit more abuse put to it, so I am leaning towards having someone else set it up for me.
7.5" rears don't like abuse very well. Add a rear cover with girdle & good axles along with your Auburn diff if you want it to last very long.
