stock gear ratio

I have a 1988 jeep cherokee 4.0L 4x4 with the NP231 tc and a BA10/5 tranny. I was wondering what gears it came with stock. The reason i ask is that i think my jeep has different gears in it. At redline out of first i hit 25 and at redline out of second i hit 45, is this normal for a stock vehicle? Also in 4wd both front tires spin but only one rear. Is all this stuff normal for a stock vehicle?

Should be 3.07's.

3.07 axle gears. I believe you should be getting approximately 27 miles per hour per 1000 RPM in 4th (not 5th) gear, so in 4th gear 2000 RPM should show 54 MPH on the speedo. 65 MPH cruise in overdrive should be right around 1800 RPM.
