1994 Toyota 4Runner SR-5 3.0L A/T 4WD

Hey all - I had a surging and low sputtering idle when the engine was warm on my 1994 4runner. I took the TB off and cleaned it and also cleaned the aux air control valve with TB cleaner. Unfortunately - the 27 year old tear drop shaped rubber gasket for the aux air control valve cover shattered in my hand into a bunch of pieces. I need to buy a new gasket. Does anyone know this part number or any way to buy one of these gaskets? Autozone wasn't able to help me out here.

Here is what the aux air control valve on the 3vze TB looks like:



And here is the shattered gasket.

After much searching, it appears that Toyota does not sell that gasket. You could make your own out of the appropriate thickness of bulk gasket material, that is available at almost any parts store or online, like this:
I just lay the material on the parts and use a small hammer to gently tap around the inside & outside edges to get the shape down right, then use a ball-peen hammer to gently tap the holes to get an impression of them. Then I use either an Exacto-knife or razor blade to complete the cuts.
Here's the general idea:
Since the part is aluminum (softer than steel), don't go to hard with the hammer. I've done this many times and it works well.

Rubber gasket. Maybe you can find some hi-temp silicone gasket material on-line. I saw some on Amazon, but 1/8 thickness which is probably too thick.
