Assuming the car is a legit, factory FM3 ,Shaker car , I would NOT ad the louvers, simply because it
is a modification to an otherwise rare and correct car (I assume) and would detract from the
value , in my opinion. If you drill those holes, somebody is going to have to go back latter on and "undrill" them , if you ever have to sell the car .
Other than that, you simply don't need them . The car would look just as impressive without them .
Just my opinion.
