2006 sierra interior color help??

I need a right switch bezel for passenger door. My truck doesn't have information label that would give me the interior color code in the glove box. Someone must have removed it. My interior is the gray color same as the dash. Which I think is pewter. The switch bezel is the gray on the bottom but darker gray or black on the top of the bezel where the actual switches come through the bezel. The only part number on the bezel is for the actual switches. Is there anyway to find out the interior color using the vin number? Or any other spot on the truck? I have attached a picture. Thanks

if you have the grey leather,its might be the same as mine,the rpo code 92l its called.. Interior trim MED DK PEWTER ..hope this helped ya
