Are you familiar with '
The Office'?
I don't expect there's enough difference between the two to make the more expensive one worth the cost. AOS, Coolant Tank, Water Pump - I go with Original. This I'm not so worried.
I'll post some info about doing the replacement later. I have an '01 Tiptronic in the garage right now and will get a look at it, but if I remember correctly, taking the bracket off with the mount is the way.
