Splash Shield Under Cover

[RazzRJB]

Can someone help me out with something. I'm trying to match a bolt for my 2006 Silverado 2500HD. This is what I need. The bolt size for the "Front Engine Splash Shield Under Cover for a 2006 Chevrolet Silverado 2500HD" 4X4 Extended Cab Full Size Bed. I've tried everywhere except the dealer. That'll be my last resort because I don't want to have to sell my house just to buy a bolt from the dealership parts dept. Thank you for your help.

Can anyone confirm the actual bolt size for the two under-engine skid plates as well as the transfer case skid?  I'm seeing conflicting reports.  Either M10x1.50 with a 25mm length OR M8x1.25 with a 30mm length.  Which one is it?
