Glenn, WADR, my GM (semi-scientific reference) parts manual shows the following for 64-71: 10-bolt: 2.73, 3.08, 3.36, 3.55 and 3.70 12-bolt: 2.56, 2.73, 3.07, 3.31, 3.55, 3.73, 4.10, 4.56 and 4.88 These are gear sets that could be purchased from GM. Other ratios were available in the aftermarket. A common misconception was the 3.08 gear was a 12-bolt. The 3.07 was a 12-bolt (43-14T) while the 3.08 was a 10-bolt (37-12T). GM Part numbers are also listed in the first link below.
