They do. If you are signed in on KLOV, when you look up info on a game, if there is a sketchup model made for the cab it will be linked under "additional references". See attached pic.
Also if signed in, you can use the main search tab on the main page of KLOV.com and then select a sketchup model search to view all models.
EDIT: LOL. notice how the KLOV photo shows the cab missing that bezel? Not the model. nuck nuck nuck.
