I had a locker (actually a Helical) installed when I had my rear end rebuilt. It's actually a little aggressive in parking lots for my taste, but works well.

With a 700R4 are you sure you want to be that steep? I'm running 4.10s with overdrive and it's about right on the highway. Remember to multiple the gear ratio by your overdrive (about 0.7) to get a feel for what it will be like, and 3.07 would be like 2.10 with overdrive.
