who cares how much was paid......they are gonna differ in price depending on a lot of things, as long as you didn't pay over $500 you got a pretty good deal. it also depends where you are in the country. popular demand areas charge more for the rears.
congrats on the new rear-end, but i don't think you can use the carrier that came w/ it for 4.88's. their are 2 splits in carrier styles between gears that if you re-gear to that ratio, you may need to replace the carrier also. that will also mean loosing the lsd. i wouldn't worry about it though, cause while your re-gearing, you might as well install a locker at the same time, it's much better off road, and won't bother your on road comfort too much.
