Just go to www.rpmoutlet.com and check them out. There are a few diferent ways to go. I went all out, but all you REALLY need is the crank pulley and belt.

RE: Underdrive pulleys
OK, 24,25% are both basically the same and are intended for 94-98 only. 42% is smaller then the 25% and allows for a slightly better hp gain, maybe 2-5, works on 99-04 only. So to answer your qustion, the year is the difference, now, there might be a 42% reduction kit for the 94-98 coming out, but don't think so. Also, don't pay for the installation, its easier to do it yorself. You will need an extra pair of hands for the tension rod, but everything else is just bolt on.
