Re: rear end question

4.11 is the deepest ratio for a 9bolt. Yes it is for your 3-series carrier. And 9bolt.com is the only place I know of to buy them, unless you have a connection in Australia.

Re: rear end question

No. The S10 has a 10-bolt. The 9-bolt & 10-bolt axles will not interchange.

Re: rear end question

They're completely different things, no parts will interchange.
