Speedometer gear

I have a 66 gto with a t-400 trany and 3.23 rear end gears and 245 x 60x14 tires.........speedo doesn't work for lack of correct gear...Any idea what gear ratio I need.......There are about 5 or so different colored gears available. I'm thinking the brown one is the one........39 tooth....
