Slant six engine EGR valve blank off plate?

@cruiser you can take what is there (if you have it) and flip it around and it will block off... Unless you are going for looks... There was a guy on ebay selling steel plates.

UPDATE: eBay

That's 1/2" stainless plate. You can cut it in half length wise and have 2 for the price of 1.
