Default IAC gasket

I took my throttle body off my 93 to clean and install new gaskets. I got a set from Jegs, I purchased a new IAC as well. The IAC didn't come with a gasket and I can't find one anywhere. I called BBK and Jegs and they have no gasket available. Where the hell can I get one.

Default iac gasket

Try jerrysgaskets.com , they have a lot things for the LT5 motor. But they do have IAC gasket, the gasket should be
the same for all throttle body's about $2.25. give them a call.

Thanks AAFC, checked the website and they are only ZR1 parts. I wonder if they use the same IAC ?? I ordered it from Corvette Central, the say no gasket is required but the original IAC had a gasket.

Looking at RockAuto they are two different parts. Not only different gaskets, but different connectors.

I thought of that but didn't know what material to buy. Choices were paper or cork. Going to order from Corvette Pacifica

Use paper on.newer motors, cork is for some applications from the 50s ,60s and some 70s cars. I also cut some rubber gaskets..... ...WW

I think the gasket set I just bought has one that I don't need. I'll check tonight.

I know years ago someone on here put out the GM part number for that gasket. It was couple bucks.

I found the original gasket number. Fits many GM models. Simple round gasket. Also, many vendors that sell IACs, have gaskets with them.. I would call or get another one from like RockAuto for example.

GM 25530697
