There is a down pipe on the exhaust that connects the exhaust system to the
Catalytic converter.  On this down pipe there is a little probe fitting that
has a metal screw on cap.  Well.. my little screw on cap has fallen off.  If
anyone has a spare or one off a wrecked vanagon, I would pay you a few bucks
for your time and postage if you could mail me one.

I have an 87 Syncro, the down pipe is only a few months old.

Thanks.
