For the ultimate in slow-mo, Mark Hinkley of Laguna Hills, California, swapped in an NV4500 transmission, which required a different bellhousing, slave cylinder, and slave mount. The transfer case is an NP231 with a 4-to-1 gearset, a JB Conversions short-shaft kit, and 2 Lo conversion. A Currie reverse-cut Dana 44 axle is up front, and a standard-cut Currie Dana 44 is out back, both filled with 4.56 gears. All that equals a 116:1 crawl ratio. The driveshafts are from Drivelines Unlimited in Irvine, California.
