[oletrucks] diff ratio - donor rear end

["Brad Kahler" <brad.kahler@141.com>]

Is it possible possible to tell the diff ratio on an 81 1-ton 
dually by vin number, or some other number stamped on the 
truck?

Worst case is I jack up the rear end and count revolutions but 
it sure would be nice to just find the numbers somewhere!

Thanks

Brad
