I have a 81 380sl, when trying to buy the wood shifter plate on the console, I noticed that all the dealers do not have the configuration that my plate has. I have 2 small red rocker type switches for heated seats located at the front end of the panel forward the shifter lever. I do not see any of these with these 2 extra cut outs. Is this something that could have been added by someone and not original to the car?.
