Thread: Rear end width questions -

Tweet

Just a little tidbit of info for the rest of you galoots....
The Romans determined that the track (axle width from the center of one wheel to the center of the other wheel on the same axle) for the azz end of two horses pulling a chariot worked out best at 4 ft., 8 1/2 inches (56 inches).
Builders of continental railroads in this country in the 19th century decided that 56 inches would be a good width between the tracks.
Henry Ford decided that if it was good enough for Roman chariots and the railroads, it was good enough for his straight axle cars, so Henry's cars were built with a 56 inch track.

Using a yellow tire crayon, make a mark at the center of the tire. Now go to the other side and make a mark in the center of the other tire on the same axle. The measurement between the marks is the TRACK. You don't need to do any disassembly to find the track of your candidate differential in this manner.

Knowing this makes it easy to scrounge through boneyards and find the exact width rear for your Henry, or any other car/truck, once you know the original track.
