Silverado Engine Splash Guard part number question...

[fallsflight]

Can anyone tell me if GM part number 15745156 will fit a 2004 Silverado 1500 Z71?  It is the Engine Splash Guard/Skid plate.  Some places I have looked online says it will and others I'm not too sure.

I found this...

11518341--------4------------ BOLT,HEX,M10X1.5X25,14 THD,28 OD,6202M,7114M,TAP,TR-PT(ENG SHLD)

I can only assume that "CK1" means "C1500" or "K1500" and "CK2,3" means "C2500" and so on...

If so, your 1500 might need part number 15203366 instead.  I'd call dealer to make sure, though.
