you probably have a 4.10 gear ratio in that rearend, I would have the rearend gears changed to a 3.31 or 3.42 gear ratio and then get some 15" wheels and tires for the back and it should cruise pretty nice for you.

Get a differential out of a junked S-10 auto. Either that, or check out the auto trans rear end ratio and replace the differential.
good luck.
