In the rear is the ultimate sacrilege: a GM 14-bolt axle in a Ford. The reasoning? The 14-bolt axle is not only cheap and easy to work on, it's also one of the strongest axles ever made for a production vehicle. Chris Bishop took care of the rock hang-ups by cutting and smoothing the bottom lip on his GM axle. He used Sky's Extreme Off Road disc-brake brackets to throw some discs on in place of the heavy old drum brakes. The 4.88 gears match the front and encase a Randy's Ring & Pinion spool for the ultimate in traction and strength. The Deaver 6-inch leaf springs hold up the rear end, while a custom traction bar (built utilizing a shackle to allow full articulation) keeps the axle from wrapping.
