Yep got another big hunk of metal in the garage, its a 3.23 LSD from an '85 firebird, it has the aluminum drums and the parking brake cables still attached. Im trying to figure out what to with it because I have a 3.73 posi in my car, with the early style discs.
Im thinking of swaping this in because my current diff has a bit of a wine and I haven't been able to figure out how to hook the parking brake up....
-Or maybe I'll sell it to a crewbie in need of a nice posi...
Kinda looking for advise, what you guys think?

You want the 3.73 and disc over the 3.23 and drum.

Parking brake is just a matter of cables.

I swear most every set of gears whines at some point.

Do you has an LSD in there now? Mix n match and build what you want. 3.73s w/ LSD. I don't think they switched the 28spline axles until 90 or something, right?

We have pretty much narrowed it down the gears. I think that if it was bearings it would be noisey all the time and the faster you go. If I keep the one I have now, Im going to go through it when I get to drivetrain class at PCC. depending on what I can afford, I'll get a new carrier but I'll probably just get a gearset.

I wouldn't give up the better gearing and disc brakes for a drum brake rear just for a limited slip. The limited slip is probably all worn out anyway.

Good thought, I think Im just gonna clean it up and sell it.
