Hi all-

Looking at this posi section on ebay.  

http://cgi.ebay.com:80/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=190248026179&ssPageName=ADME:X:RTQ:MOTORS:1123

It is just the limited slip part.  Would this fit into my 68 firebird stock rear housing?  Currently have 256 open in an 8.2" (I think).  I would ultimately like to upgrade this to 3.55, or 3.42's with this posi carrier.

Thanks
