If it's the EGR Block off Plate try Champion Heads they
make them!
why would you want to block off the egr, anyways? when properly functioning, it doesn't hurt anything.
I made my own...think it cost me a few bucks...just get 1/8" aluminum...make a template for the cover...transfer to aluminum...cut it out...then either paint it aluminum or polish it...whatever...
