Im looking for a set of the Dana Marine billet 1" spacers that fit between the manifolds and the riser. They have an 02 sensor port in each one and come in a pair. There part number is EX-002.

I cant find a set online, available anywhere even at Dana marine themselves. If you have a set for sale please email me at [email protected]
thanks!

Dana doesnt have them? Really?

Whats their lead time?

When I called them today he told me they didn't have any made and didn't know when they would get around to it. He also told me there's no other way to mount an 02 sensor to my manifolds...

Bump. How about even just one laying around I can borrow long enough to data log my motor then I'll send it back to ya?

I have a set for stock 496 exhaust....dunno if they fit Dana...

You can prob have any local machine shop make you a set in a day or so just as cheap. They are very simple to do.

Do u think a 1" thick open spacer with a hole in one will suffice? Looks like the Dana one had 4 holes in the middle , one for each cylinder..

I think it will work fine personally, your really averaging 4 cylinders anyway in either configuaration
