Where can I get the gasket for the Vac block on top of my SC? I am not sure where to look or what it is called? Thanks for the help

Your best bet would be to find a dealership parts guy that'* good and have him help you find it in the drawings. It'* likely you are going to find out it'* no longer available and then you are off to make your own.

Hello Bill,
I tried gm gasket maker and it worked for a little while but just didn't hang in very well. How would I go about making my own gasket? Thanks

You can get a roll of gasket material at the parts store for under ten bucks and with a razor make your own gasket

That'* what I did for the jag. You can buy two different kinds at a normal auto shop; one more geared for water pumps and one general purpose. The one for the water pumps I believe is blue, and the other is gray. I used the gray one to make a water pump gasket for the Jag, and it held up beautifully. I wouldn't hesitate to do it again.

If your talking about what I think your talking about, isn't that a O ring?
