I'm running a 904 from a Cordoba and 8 3/4 rear differential with 3.55 gear ratio and I need the correct color gear drive to use in my 65 Plymouth barracuda fastback gasser project. I have a black gear drive but I think someone mentioned I need a red gear drive. My tires are 27 inches

What year is the transmission?

At some point they changed pinion gear types, I had a '76 that had the newer type.
 
I will probably need both the yellow 33 teeth and the green 34 teeth just to be sure cuz i think my tires are either 27.4 or 27.9
 
Here is what I have right now. Notice no cable attachment sticking out where cable goes on my transmission
