Rear axle assembly - reccomendation?

Ok, guys. I have gotten some great advice on this forum but so far, looked at several options (both in person and on line) but for multiple reasons, I haven't bought one yet and I'm back with my hat in my hands to ask for advice on a slightly new direction.

I'm leaning strongly towards just writing a check for something off the shelf rather than pulling one from the junk yard and rebuilding it.

The following are my criteria but if anyone has ever purchased something similar, your experiences (and opinion of the vendor/product) would be HUGELY appreciated.


-Limited slip (no locker)
-3.73, 3.90 or 4.10 ratio
-strong enough for a healthy small block that may get slicks at some point.
-large bolt pattern axles

Here's where it gets tricky. These are "wants" but not requiremens:

-Possibly narrower than stock width (if that might allow an extra inch of rubber!) but I'd rather not have to move spring perches... perhaps that's not even possible...

-Doesn't have to be a Mopar axle. I looked at the Ford Explorer axle assembly options but I'm not up for cutting/welding, fabricating parking brake system, etc.

-Disk brakes (if feasible)?

-But....I'd like it to be more or less "plug and play." I have an absurdly full schedule (like an idiot, I went back to school... :violent1: ) and if it requires any serious labor, it will take me years to get through it.

Am I totally off my rocker?
Where would you start looking?

Thanks a million to anyone with a lead. :prayer:
