That is interesting. Thanks, Dan! I have a question somewhat related. You posted (I believe it was you) a link to McMaster-Carr for new manifold studs. Could you repost that here please? I feel like I am looking for a needle in a haystack on their site. Thank you.
Also, @krazykuda once Dan posts that link, IMO, you should turn this into a How To so the information will be saved. This is really good info that's hard to find otherwise.
