Gear ratio of a 1966 Beaumont


Does anyone know the gear ratio of a 1966 pontiac Beaumont three on the tree transmission?

Edit: I can't find a code anywhere on the axle

Easy to find out. Jack up car and mark tire and mark drive shaft on a posi rear turn the both tires 1 full turn and count the drive shaft turns, if it goes 3 1/2 turns it is a 3:50 if it goes 4 1/10 it is 4:11 etc. For non posi rears, lock one tire and turn the 1 tire 2 full turns and count drive shaft again and same results if 3 1/2 turns a 3:50 etc.
