Yep, I just got the bad news as well...
Car won't be done till Wednesday... Something has changed and it's more than the ring and pinion that have to be changed. Make sure Subaru Parts is quoting you ALL of the parts you need. It also sounds like your dealer is quoting the Diff assy (for $1800). That's the same price I got.

what a drag. I've been W/O th ecar for a month...
