4kq transmission parts?

[Rebecca and Peter Lines]

Before I call every single OE parts place on the links page,  can anyone
recommend a source for quattro transmission parts?
I was disappointed to find a couple of cracked teeth on the sliding reverse gear
of my trans.  Looks like a sharp impact under partial engagement of the reverse
gears.  The 1st/2nd operating sleeve also has a couple of cracked teeth.  I don't
remember ever hammering it into reverse, but I suppose its possible.  If it was the PO,
then I have been driving around with cracked teeth for at least 90k miles.  I keep
telling myself that it's only reverse, but it's against my better judgement to put 
this thing back together with cracked teeth.  Seems like a time bomb...
The local dealer wants $400 for parts.  Ouch!
