JUST a limited slip

As fun and cool as the idea of scoring a completed Explorer axle in 3.73 with disc brakes, flipping it, getting the angle set IS..... (sound of heavy breathing) what is the most simple way to get traction to both rear wheels of a relatively stock 99 Ranger 4.0 with a 5 speed Automatic trans...never gonna go off road, drag race, do donuts....just don't like wheelspin on a rainy day.
The 3.73 is not out of the question since opening the axle on a 300 K truck suggests it might be time to freshen up things....but it's just a daily driver.
The real question is since some of the off-readers sort of dog the LS would do the trick OR would the long term (truck is very nice and will be handed down) fix be one of the lockers. I have used a locker in race cars but not on the street. If the prices are not that steep - which aftermarket unit has the best reputation.

I have a 4.0l with an R6, L/S 8.8" 3.73 and wheels still spin on wet pavement, lol

Look at your door label for which axle you have: http://www.therangerstation.com/tech_library/axle_codes.shtml

If yours is Open and not L/S(limited slip) then you need to find one that is limited slip, auto wreckers are of course the least expensive.
You can swap the whole axle or just the guts

Wheel slip

Yep, I can spin 'em on dry pavement too! The idea being just to make it harder, safer, or just not tick me off...

It's an open 3.5 - bought the truck
new, has just over 300, 000 miles so buying a wrecking yard explorer axle and rebuilding it on the bench before installing it is also a way to go.
