Man, get to a junkyard! Seriously, you've got some of the best U-Pull-It salvage yards around.
Try the one on the left on the way out to Cecil Field, what is that road, Normandy? It's got a yellow or orange fence around it. I used to get all kinds of (Saturn) parts from there and they are pretty reasonable. It's well before the titty bar, probably 4 miles from 295.
Sounds like the perfect opportunity to upgrade to the Explorer rear end and get disc brakes as a bonus.
