Need Interior Trim Color Code

[Ex Euro Driver]

Hey all, been to the dealer 2 times with the VIN trying to figure out an interior trim code. I know what the code is for the seats, door cards and flooring. What I need is the code for the pillars and headliner. The only thing the dealer can tell me is that it's "grey". Any ideas? I need to match the paint for a speaker install. Thanks in advance.
