I posted this over at Team Camaro and didn't get any feed back, so I was hoping someone here could help me out. I've got an original GM vacuum switch that leaks out the bottom. The diaphram is fine, I believe it's the cup seals in the valve body. Has anyone ever rebuilt these or have pictures of the internal parts? If so, how did you get it apart and where did you find the seals. I don't want to cut the steel ring around the diaphram. I removed the crimped washer off the bottom of the shaft, but still can't get the seals out the bottom. Thanks, John
