Default Dang, Lost Some Info Re: 4 Speed Trans...

Need a little help guys.
Somewhere, buried in my garage is the original Pontiac info regarding which rear end ratios determined which transmission a car came with. I just cannot seem to locate it. I believe the change up between the wide ratio M20 and the close ratio M21 was somewhere between the 3.36:1 and the 3.90:1 rear end.
Does anyone have this info handy that they could share with me?
Thanks, Greg
