Alright, I sound really stupid. And I must be blind or something, but I have looked all over the rear differential (the housing in the center of the rear axle, correct...?), and don't see two bolts on either side anywhere? I'm really confused.

If anyone (Steve!?) could post pictures, I would really appreciate it. I am at a total loss. I don't know what to do. This is all I need to be to complete my 90k service (extended over 10k miles!). But this way I will be on track for my next 30k service @ 120K miles.
If not, then I am getting a digital camera next week, and I'll take some pictures then and post them. Everyone says that you can't miss the bolts, well I must be doing something wrong. I can't find them for the life of me.

Thanks everyone (and ANYONE!) !!!!

I suppose I could just take it in.....!

big ol Allen head "plugs". One half way up the side of the diff (don't remember which side). It takes a 14 mm allen head socket - get one with 1/2" drive. Obviously, the drain plug is near the bottom of the diff. Make sure you remove the fill plug first.

The fill plug is at the drivers’ side of the differential, halfway to the back and just above the upper half in height.
The drain plug is at the passenger side, almost at the rear of the differential near the bottom.
Both bolts are Allen head bolts and are leveled with the differential housing (the bolts do not stick out the housing, but are leveled with it).

If you want, I can send you some marked digital pictures; no problem.

greetingz,
