Well, thanks for the link to car-part.com! It helped a lot. I ended up calling a yard in Eugene, which is only about 60 miles from me. I was just getting ready to pay 300 for one, and go pull it. Then I decided to make a phone call to another yard (bigger) and they had one for 250 and were willing to ship it to a business address for $FREE$!! According to the VIN, it is a limited slip, but no info on gears. The yard is going to verify it is 4.10's before they ship.
I know the factory trac lock isn't a "locker" but it is a limited slip, and for the amount and type of wheeling I will be doing it should be great, and I won't have the unpredictable handling and clicking of an auto locker.
Oh, and this axle is supposed to have only 28,xxx miles on it!
