I have a 9" out of a 79 f150 with 4.88 gears and a posi. pm me if interested. Its sitting in my garage waiting to go in a project but I just got some Dana 44's instead.
It's hard to plant 500+ HP with an 8"..... It can be done..... Once maybe twice :shhh: That's why I need a big bearing 9" to put the detroit and a set of 3.90 gears in it:yelclap:
