tpi plenum extension part #s
I was reading the article about polishing engine parts and I wanted to get the corvette aluminum plenum extension as my car is missing an extension piece.

I went to Gmpartsdirect.com and entered the P/N for the extension screws and it came up referring to them as bolts with a listed price of $2.42 each. That seems like a bloody expensive screw. Is that the correct piece or does the article have an incorrect P/N?
Thanks

Yes, that's the correct part number. I upgraded to an aluminum plenum extension recently and bought three of those.
