I know there are several people (myself included) that have asked about block off plates for the EGR valve. No one that I've found makes one specifically for us, I've seen someone mention a EGR plate from summit but I wasn't able to verify, and the ones my local parts store aren't anywhere near right.
On a whim I was at a local ACE hardware store and they had a Fuel Pump Block off plate for a Ford 351 that looked like it'd fit perfectly. The predrilled holes were damn close. With one bolt in, the other was just a hair off so I took a cutoff wheel to the end of the plate to open the one end up and a pair of scissors to do the same to the gasket, and VOILA!
Link to Summit, tho most parts stores should carry or be able to get for comperable price. -->
