Section 1: Introduction
What is a 1967 A-Body Car?
1967 A-body cars are a family of vehicles produced by General Motors in the mid-1960s. They include the Chevrolet Chevelle, Pontiac Tempest, Oldsmobile Cutlass, and Buick Skylark. These cars were popular for their sleek designs, powerful engines, and comfortable interiors.
What is a Rear End?
The rear end of a car is the assembly that includes the differential, axles, and wheels. It is responsible for transmitting power from the engine to the wheels, and for providing stability and handling.
Section 2: Essential Components for Rebuilding a 1967 A-Body Car Rear End
Differential
The differential is the heart of the rear end. It is responsible for distributing power to the wheels, and for allowing the wheels to turn at different speeds when cornering. The stock differential for a 1967 A-body car is a 10-bolt unit. However, many people prefer to upgrade to a 12-bolt differential, which is stronger and can handle more power.
Axles
The axles are the shafts that connect the differential to the wheels. They are responsible for transmitting power from the differential to the wheels, and for supporting the weight of the car. The stock axles for a 1967 A-body car are semi-floating axles. However, many people prefer to upgrade to full-floating axles, which are stronger and can handle more abuse.
Wheels
The wheels are the final link in the rear end assembly. They are responsible for providing traction and support for the car. The stock wheels for a 1967 A-body car are 14-inch steel wheels. However, many people prefer to upgrade to larger and wider wheels, which can improve handling and provide a more aggressive look.
Section 3: Tools and Equipment
In addition to the essential components listed above, you will need a variety of tools and equipment to rebuild a 1967 A-body car rear end. These tools include:
