Sorry folks but it's just a shortened F60L chassis. As Hanno suggests it's been done by moving the axle forward and chopping off the excess rear chassis. Simplest and tidiest way to move the axle forward is to move the rear spring hanger to the front spring hanger position (they use the same rivet pattern on Fords) and move the front spring hanger forward correspondingly. This results in a wheelbase close to 115" which tends to play tricks with the mind! As Mike says - "the 115 inch wheel base seems too much of a coincidence for a farmer-shortened chassis." Of course, once you're familiar with this mod it's easy to detect the numerous inconsistencies resulting. For example, the triangular rivet pattern for the overload spring stops located curiously BEHIND the rear spring hanger!
