Inliners International Forums General Discussion Drive Train What is the early Saginaw 3 speed OD ratio

Does anybody know the gear ratio for 1st, 2nd, and overdrive for the Saginaw 3 speeds from around 1955 to 1962 Chevy models.
Also, were there more that one gearing sets for these old 3 speed OD's ?
I don't even know, if these were all Saginaw or if some were Muncie ??
