Chevy (Muncie) speedo gear chart?

[47convert]

Does anyone have a link to a chart for Chevrolet Speedo gear selection? The plastic speedo gear in the Muncie 4 speed in my 60 ElCamino turns (sometimes) when I turn the output shaft, but seems to be slipping or not engaging properly and with the speedo cable hooked up, it doesn't turn at all. The gear in the trans is good and appears to be in the right location on the shaft and the plastic gear looks like it has all it's teeth. I want to replace it, but don't know what color gear to buy. The one I have now id red, but it's just one that a friend gave me since the 4 speed used to be in a race car and had no plastic gear in it when I got it.
