Wrenchfetcher,
Thanks for the info. Can you supply me with a part no. for the diaphragm? If not can you give me the name of the Chevy dealer where you purchased it. My local dealer just laughed when asked for his help.When I removed mine I found the source of the oil. My diaphragm was toast.If I can't find one can anyone tell me of another fix. Maybe a mechanical linkage of some sort?
Desperate I am,
JMH
