replacing the clutch master cylider on a 4000 quattro

[Rusty Rae <rrae@cotl.com>]

Okay the clutch on my 4000 is sticking half way down, everyonce in a
while. I called max at AVS, and he said that I need to replace the
master cylinder. Anyway I ordered a new master from Max. So I have never
replaced the master cylinder on an audi. Any suggestions on where to not
go wrong? Max said that it is just 2 bolts and pulling the old one out
and replacing it. I don't think it is that simple. i imagine that I
would have to go in through the fire wall? Well wish me luck. 
thanks for he help in advance.
