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

Thanks. Just made an offer on eBay for one. Appreciate the help. BTW, are you a Marine? MOS?
