Help with EGR chambre gasket?

[Hot Air Beast]

Anyone know of a source for an EGR chambre gasket - AC Delco part no. 25515937?

When you look up EGR Chambre gasket that is the part number AC Delco gives but when you go to search on the part no. it says it is not a valid number. Go figure.

This is the last piece I need to complete my rebuild. I figure worst case I'll cut one outta some cardboard (just kidding but getting close to losin it here).

I have checked G Body Parts, GM Direct, AC Delco, Poston - all without any success - most don't even recognize EGR Chambre as a part.

There are two gaskets associated with the egr valve. There is one between the intake manifold and the extension block. It's long and thin with a square hole in it. I could not find this one so I just used some copper rtv on the old one. You could buy a small sheet of hi temp gasket material and cut your own. The other gasket is kind of triangular shape and goes between the egr valve and the extension block. I was able to get this one at Advance Auto Parts.

Pretty much what I figured

Thanx Gary. That is pretty much what I figured. By the way - thanx for making a word version of your window sticker. I have been adding in the options I have and it should look pretty good when my ride is back on the road. Pricing will be way off given I'm in Canada but it still look way cool.

Thanx again.
