I've got some different numbers as well....in '69, (3) different 3-speeds were offered; (1) 3-speed fully synchronized, (2) HD 3-speed fully synchronized, (3) 3-speed overdrive. I don't know what each of these trannies are, saginaw or the like, but for tranny (1)...specs are

(1) Standard on all 10-20 series except with 307 or 350.
1st...2.85
2nd..1.68
3rd...1.00
Rev...2.95

(2) HD tranny included with with either 350 or 396, and on PE20 models with a 307 or 350. Standard on all 4WD applications (KA10-20)
1st...3.03
2nd..1.75
3rd...1.00
Rev...3.02

(3) Available ONLY on C10 models with the 4.11 rear axle.
1st...2.00
2nd..1.18
3rd....0.70

Either way you slice it, there really isn't that much difference gearwise until you hit the OD tranny.
