20 years ago I bought a 55 Gasser. In the trunk was this Shiefer/Hurst Quickchange Rear End. Cleaning off a shelf and Voila! Here it is for sale! Included with the Quickchange are (2) Sidebells, (2) Disc Brakes, (2) Calipers w/hoses, (2) Axle Flanges, (2) Bearing Retainers, (1) Yoke w/U-joint and (2) sets of Gears.
