Limited Slip
JMC Motorsports provided us with a used 8-inch rearend from a '68 Mustang, perfect for our swap. Used 8-inch cores are becoming harder to find. However, there are many sources. Currie Enterprises can build you a new 8-inch axle housing and differential. If used is more to your liking, check with Mustangs Etc. or Memory Lane Salvage for a rebuildable core.
Randy's Ring & Pinion provided us with a complete 3.55:1 ring-and-pinion rebuild kit, including bearings, seals, gaskets, O-ring, shims, and more. We enlisted the help of Jason Hughes of Hughes Differential Systems in San Diego to freshen up our tired 8-inch chunk. When Jason knocked the differential apart, he found 3.55:1 gears and a peg-leg arrangement that was rebuilt not long ago. He saved the gears for another project and built our differential with a new limited-slip and 3.55:1 gears from Randy's.

When you're building a daily driver, don't spend much time on cosmetic detail. We blasted this rearend with Simple Green and a scrub brush, then nailed it with a sander and Eastwood's Black Satin paint.

The fresh 8-inch housing is installed without the heavy 3.55:1 third member to save weight during installation. Jeff secures the leaf springs and installs new U-bolts with media-blasted and painted spring plates. We have opted for Grab-A-Trak gas shocks in all four corners for smooth ride and crisp handling.

JMC Motorsports uses Permatex's The Right Stuff to seal between the differential and axle housing. Jeff opts for The Right Stuff on both sides of the gasket and around the studs. Nylon-lined locknuts secure the third member.

Jeff installs new axle seals and lubricates them with engine-assembly lube before installing the axles. New axle bearings afford added security and long life.
