really could use one of these if anyone has one they'd like to sell..

I might have one, can you give me the part# so I can confirm it.

It is-

LT4 knock module 16214681 $27.66 (as listed on GM Parts direct)

is the one you have new?

I do have it and it's still in the box never used. The GM parts direct price is actually $31.02 plus $7.95 S&H total $38.97 assuming you don't live in N.C. then there is sales tax, anyhow I'll sell it for $20.00 plus shipping. Shoot me a PM and I'll give you details if your still interrested. Thanks!!
