Re: gear ration
Yes I do have the dana 30 in the front, it did have the 258 motor, currently
it has a 350 in it. I was trying to avoid having to remove the diff cover
and do the math, but that seems to be the safest. Thanks for the help.

Re: gear ration
All you have to do is jack up one tire and put a mark on it and on the
driveshaft and turn the one tire two turns while counting the driveshaft
revolutions.
The spider gears mean you need to turn the tire twice with one tire only
turning.
Mine turned the drive shaft about 3 1/3 turns which gives me the common
3.31's.
