Axle ratio help

[Mijeeper CJ 7]

I've got a set of axle out of a 1978 F150 4x4. It looks like a Dana 44 front & a 9" rear. Just wondering if anyone knows what gear ratio's were available for that year? or where I can go to find out this info.

Thanks.

Most are 3.50 factory. Pull the cover on the front and it will be stamped on top of the pinion and on the side of the ring gear.

or if you have them in your possesion just give the pinions a spin, count the revs and do the math.
