It would take some searching to give you all the right numbers, but Dynon can get you the right stuff real easy, just give them a call (they might be able to look up my order for you even). Make yourself a list from the Viking site of what and where you are measuring, they will convert it into an order. When I ordered, there was one they had that was not on their parts list, no problem if you call. I think some of the threaded hole sizes have changed with the new manifold, so order what fits yours.
