Mopac on 16th ave has em, the Wrangler Extreme kit.
One thing to note, is there is an additional part# that you need for your expansion bottle bracket. Unless you want to hack up the old shroud to salvage the bottle bracket.
I highly recommend this, on mine, I noticed HUGE power gains, and an extra 100km to a tank of gas!
I put the temp probe in the upper portion of the rad, and set the thermostatic controller to the lowest setting. I ignored the a/c compressor tie in, and ran an ignition sense wire from the cab fuse box, into which I put an switch so I can turn the fan off for deep water.
You'll like it, I promise. I recall it was in the $300 - $350 range from Mopac.
