'04 MCX 350 KNock Sensor Part Number?

[deminimis]

Does anyone know the correct part number for the knock sensor on a 2004 MCX Vortec 350HP engine? Mine is a bit corroded (not that it really matters) and figured I'd swap in a new one just 'cause. Thanks.

I need that same #, oddly enough. I started looking into it yesterday and was going to call the MC dealer, but if someone has it here...

I don't know the part #, but I'm pretty sure this is it.

found 3 part #'s here http://www.charlotteskiboats.com/mastercraft_parts.cfm , not sure which one fits your application

81551291
81556015
81551392 says it fits 06-07 mcx??

Larry at Indmar say it's 556015 (81556015 above). Although that's actually for a LT1, he assures me it is correct for our Vortecs. If that's accurate, then it's Delco 10456126 (for you cheapskates like me -Rock Auto =$28 and change)). I'm gonna trust ol' Larry.
