Clutch Master Cylinder

[SAJanesick - Bellsouth]

A flurry of activity.  Maybe it's the weather.

Regardless, I've been poking around under the hood over the last week catching up on some long overdue work.  I replaced almost all of the 22+ year old vacuum/pressure lines, cleaned many contacts and sensors (engine speed sensor looked like one of those iron filing/magnet toys from days gone by) and things are running measurably smoother and stronger.  I even surprised a Corvette at a stoplight yesterday evening - at least through most of second gear.

Of course all those improvements came at a price and it seems the gods have demanded a clutch master cylinder as sacrifice.

I poked around AutohausAZ.com and they do not show a listing for a CMC under 200TQ20V parts.  Even their sales people swear they do not have the part and that there is a difference for the 3B engine.  I replaced the CMC in my silver car 4 or 5 years ago and AutohausAZ was the likely source.  They do show a CMC listing to fit a 200TQ with the MC engine:

 https://www.autohausaz.com/search/product.aspx?sid=tz51o345ypxpzq5515gwjy55&makeid=800002@Audi&modelid=1007277@200%20QUATTRO%20TURBO&year=1991&cid=15@Clutch%20Parts&gid=1996@Clutch%20Master%20Cylinder 

It appears that  4A0 721 401 might be the OEM part number for most '91 100 and 200, but I'm looking for additional confirmation before ordering.

Anyone out there know if the CMC for '91 100's and 200's (specifically 3B 200's) are truly interchangeable?

Thanks for any assistance and the intangible moral support I get in knowing I'm not the only one fool enough spending time trying to keep these cars on the road.

Later...
