Question M-20 speedometer gears

I have a 67 C-10 with a Muncie M-20 4spd tranny. I have changed the rear end from a 3:73 to a 3:07. The tranny currently has a 19 tooth steel one piece gear. I will be using 235/75/ R15 (29 in dia.) tires. What speedo gear do I need to change to, and where do I get them. The two GM dealers that I went to do not have info that goes back that far. Please help! Todd
