REAR SUSPENSION:

The following is a general list of rear ends and their dimensions to help narrow the search for a possible candidate to replace the torque tube rear end or just get a better set of gears for highway driving.

Advance Design Trucks seem to be using rear ends with widths ranging from 58"- 62". I'm not sure of the Task Force width ranges at this time.

Contributing information were Bob Welch, J Forbes and various locations throughout the Web and Automotive Magazines.
