Cagliostro

We recently replaced the tires on my wife's 2005 Sienna. The place that did the work also checked the alignment. The front was slightly out and they fixed it. The back is also slightly out, left toe 0.42 (spec -0.16 to 0.41) and total toe 0.59 (spec -0.03 to 0.53). However, they said to fix the rear, they need a special $69 "shim kit" and another $85 in labor. Is this legit? The local toyota dealer said they don't sell a "shim kit." I found a place on the web that says they do but it only costs $13. Thanks.

Thanks for all the suggestions. I took the regulator out today (and cut myself nicely in the process:)). I'm not sure what happened but the regulator somehow broke into two pieces so that the piece with the teeth that fits into the motor is no longer connected to the rest of the assembly that actually connects to the window. I'm going to order a new regulator assembly but I'm confused by all my choices out there. There seem to be two levels, one at $60-$80, the other at ~$160-$180. Is there any reason not to go with the cheap one?

The driver side rear window on my 99 Camry stopped staying up one day. I can manually pull it up but it usuall falls straight back down. I've taken the inside of the door off and can't see anything wrong with the mechanism. The motor whirrs when I press on the controller but it doesn't move the window at all. I see that you can buy replacement window regulators, regulator assemblies, or just the motor. Is there any way to tell which of these I need and how hard it the repair? Thanks.
