EGR Block off plate

Alright, I know you have to have a block off plate for when you remove the EGR Valve, but I was wondering if there was a specfic size that had to be use.
Thanks

The size that covers the 2 holes and can extend to the bolt holes. If you're making your own, just trace the stock valve, or wing it. Just looking at the machined surface of the intake should give you a pretty good idea of what you need.
