i would doubt a 4.30 rear gear would have been used on a 1/2 ton application.

I am just going off of the info posted above, the axle code numbers get bigger with the ratio numbers, so 27, which is bigger than 25 (did I have to say that lol) would have a larger ratio (or smaller, I have been reading all night, and math is not high on my list of things that I care about right now...)

Im not sure, just throwing in my .01 (yall dont even get 2...)
