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.
