Oh yeah, I guess I should clarify since I haven't actually posted this yet. On Sunday I won an eBay auction for the differential and associated parts that I need in order to fix my car. $630 is a lot of money, but it's cheaper than I've heard of almost anyone getting these parts, and it's at least $300 less than I could get them for retail. So it's a good value.
I anticipate being up and running in a couple weeks max.
