Bummer -

As mentioned above, there are several routes to a 9". Unless you're really attached to an "all GM" approach, you can get a rearend complete from Currie with a bullet proof 4.56 and Explorer disc brakes for $2,780. Ton-o-money, but it bolts right in and you will never have to address this component again this side of 800HP!

I'm a Chevy man - and reading through your saga makes my heart go out to you as it sounds like someone took you for a ride - but it sounds like the housing is trashed and there's nothing there to build from so the Ford 9" may be a good fit. To start from scratch, i.e., new carrier, tubes and spring mounts, with a 10 or 12 bolt will run a lot of money as well.

Good Luck,
Glenn
