FYI, Jetta Mk2 had the exact same bellows, and I typically find them with ease at the local german auto junker.

Trevor,

If the bellows is ripped it won't hold a vacuum, thus won't work. You may not need the pricey diaphragm at all. Try a bit of Automotive Goop in the tear. That's kept mine working for the last few years.

I would like to find a new/used rubber bellows piece though.
