I have two of the 66-77 Bronco housings. Should fit my Mav's with no problems. One of my Mav's has the '57 rear end with the smooth back. Thanks for the list.
I have just purchased a 9 in from a 66 bronco I can't wait to get it in this winter mabey a little sooner if the 8 in breaks I doubt it will though.
