Spoke too soon...I found an EGR.
The World Wide Web is a wonderful; thing...
I found a company in California that had my mystery EGR valve in stock!
I strongly suggest writing this number down in the back of your Chiltons manual just in case you ever end up like me trying to hunt one down. I thought this was going to be an easy part to find. Boy, was I wrong!
