Stainless AIR Block Off Plates

Anyone know where you can get block off plates for the headers where the AIR attaches in stainless?

It seems like that would be a fairly easy DIY project if you had the material. Or, maybe a machine shop?
The LT1/LT4 owners might have a source...I recall owners of the '94-96 Impala SS frequently doing it.
Do an internet search using "stainless AIR block off plates" as the keywords. I found plenty of potential sources...

Tried that but also used LS1 in the search, only came up with aluminum. Wonder if the LT1's use the same gasket, which would show the same part would work.

I made some out of aluminum for my sons camaro and they have been on it for a year or more and they are holding up pretty good using the stock gaskets.

Trace out the pattern on a piece of paper and transfer it to the aluminum and cut it out roughly. File it to fit or use your dremel to make it fit.

(It says for F-body, but they fit, and they are stainless).

Just a quick note - almost every air tube that I've seen break off had a block off plate that was too thick and used stock length bolts to secure the plate.

This "pendulum" sits out on the end of the now unsupported tube and after enough time the harmonics, moving the tube back and forth, break the tube off - usually just outside the weld.

The best solution/prevention is to gusset the tube and always use the lightest, thinnest material and cut the bolts to a minimum length.

Hope that helps.
