I'm trying to find the metal clamp that holds the master vac check valve to the firewall.  Does anybody have one they would sell?  Thanks!

Thanks- I didn't know about that site.  Any clue when if the black ones will be available again?  I'm guessing you are in the know since you have the web address in your signature.

I have lots of bits and pieces like that, although the rubber ring bit are likely in poor shape. PM me or send an email to z240shaw.ca to discuss

I'm just looing for the bracket.  I have the check valve/rubber
