Looking for 2 Formula S fender emblems

Ha, there's always something more to learn.

So this car is not a factory Formula S. But it's got the 8 3/4 rear end & Sure Grip & I just added the "cooler" hubcaps with the chrome lugs exposed (pic below) ... so I'm close to S clone territory. Does that mean I'll need to (very carefully!) create my own stud holes for the S emblems, and therefore can use either the vertical or horizontal version? Or are the stud holes already under there and I need to make sure I get the correct alignment?
