need speedo gear

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 right now but i don't know how many teeth it has

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
