Rear Differential, gear replacement, and locker choices

I destroyed gears in my rear differential. I'm looking to put a locker in and I need some choices here. I'm looking to stay with the stock ratio {I do a lot of highway driving but I still like to hit some good trails on the way} so I don't have to fuck with the front end.
Where can I get parts? What do you recommend? What brand locker? Im not looking to have to get a compressor if I can avoid it...
What size differential and gear ratio comes stock?
2011 Toyota Tacoma Sport 4x4

 

wow, how did you manage to grenade the sport's "8.4" in rear diff!?!?!

call up east coast gear supply... they will get you what you need, and ARB air locker... otherwise stay away from a lunchbox locker, and go with something like the detroit trutrac.

 

I have a set of stock 3.73's for sale cheap, $75 plus shipping. That includes the rings and pinions with only 5k miles.
