66 impala stock Rearend

I wan't to put a Posi Rearend in a 1966 Impala Sedan. Right now it has a 406 SBC with a Turbo 350. Can anyone point me the right direction as far as what type of Rearend came in a 1966 Impala? I know it's a 10 bolt.. I would just like any help finding out what's in it now? And a good choice what to put in it? Cost? Dimensions?

Thanks

Probably an 8.2"
There are aftermarket posi carriers available.

You sure it is not a 12 bolt rear? If it is there are many manufacturers to go with from strange, moser to powertrax

If you're sure it's a 10Bolt, it will be an 8.2" Ring gear Diff with 28 spline axles. You can get an 8.2" Posi such as these, the (Powertrax) is for use in the Open type carrier to convert it to a Posi, sort of like a minispool as such you don't have to remove the carrier & gears to do it>

I'd try Ebay for a better price. Or if you could find a 12 bolt Rear housing it will be easier to find a Posi carrier used or new.
Look at this link and it will show what will interchange into the 10 & 12 Bolt housings, from which vehicles, gear ratios etc.. Pg.72 & 73.
