I don't think a 4 speed was installed in the B2's but I could be wrong. All tech info like gear ratios are listed in the tech thread at the top of the B2 forum.

If your tranny code is X (check the sticker on your door) the tranny should be a TK-4. First gear is 3.96. So first gear 3.96 X t-case low range 2.48 X your axle gear ratio of 4.56 is 44.78.
