Yes, those part numbers would help. Thanks. I've got the plate off now and the
foam gasket is intact and still attached to the intake. The plate came off very
easy. I didn't have to remove the throttle body from the plate itself, so
replacing the spacers won't be an issue, but the part numbers will help in
future. I'm putting a new egr in also. I found a piece of the poppet down in
one of the holes while scraping and vacuuming. so it was all worth it. Don't
know why I was so afraid of this project before. Quoting DAVID MORRISON
