I have saginaw 4 speeds and 3 speed overdrives that were red, orange, and black when I got them. I have no idea if any were the stock color. The 4 speeds came in four different ratios distinguished by the number of groves on the input shaft.

Beater, where are the lines/grooves on the input shaft? On the splines, the part that fits into the pilot bushing, or the stationary part that the input shaft rotates in?
