1966 C10 speedometer gear question.

I have a TH 350 with a 19 tooth nylon colored (yellowish) in my trans. I’m fixing the leak with a new bullet. My speedometer reads 50 when the truck is doing 55 according to GPS so it’s 5 mph off.

What color or amount of teeth gear do I need to correct this? I would like to correct this at the same time I’m fixing the leak?

I have 17” tires and a 373 rear end.

Thank you,

Greg
