Would someone please do me a favor and check the part number on the engine cover on their 2004 (preferably) Yukon XL with Vortec 8100?

My was removed and never replaced at a dealership and would like to know what elusive part number I should be looking for.

The part number is printed on the inside of the cover (molded into the plastic). It's very small but it's there.

Thanks.

This looks to be for the 6.0L. Need the 8.1L part. Way different based on the picture I see and what I used to have... thanks for the effort!

Unfortunately the cover is vehicle-specific as well as engine-specific. I've not found one for the Yukon XL. :(
