Need to know gear ratio.

[az88k5]

So I have a set of gears out of a 1970 dana 44 drum front axle. The #'s on the gears are as follows, 323 70 Dana 18520 A3D70 45-11

Thanks for any help.

45/11 = 4.09.

I doubt im right but I think the last numbers give you the ratio, 45-11. Divide 11 into 45 and you get 4.0909 so I guess the'd be 4.10 ratio. There's a pretty good chance that I just pulled that out of my ass though, i'm just guessing.
