Currie, Moser, and any number of other companies make a 9" housing with factory brackets for Camaro's and Firebird's.

You can support one of the TGO vendors such as www.spohn.org who will also carry one of the aftermarket bolt in diffs.

Re: ford 9 inch

Are you looking for a housing and axle package or a complete rear end? You can get the housing and axle package and use a junk yard center, or get a complete rear end. The center chunk is the most expensive part.

Re: ford 9 inch

Mine is all Currie stuff minus the center section which I got local. Everything bolted up good, just a little grinding on their torque arm bracket to fix a spot where it was hitting the center section. Not sure if they've changed it by now.

Re: ford 9 inch

The above picture should include the axles as part of the diff package. Order it with 31 spline axles then find a junkyard center section with a 31 spline posi and hopefully a gear ratio that you can live with and pop it in.
