I see you got the pre-cat, a day earlier than I anticipated. Thanks again. The two studs were removed to fit in the box. I'm sure you can figure out how they go from looking at the old one. I think only two holes are threaded. I did not find any gaskets and I don't think that there are any other than the copper gasket at the y and the metal gasket at the manifold both of which you should be able to re-use. I hope it fixes your issue.
