NOTE: Starting in
1957 ALL Series 4000 and 6000 model wheelbases are lengthened by 2.5 inches
to provide for the use of larger size tires without causing interference
between the wheel and the toe pan on extreme turns. This wheelbase change
is accomplished by moving the front axle forward on the springs, shortening
the front overhang. Front fenders with wider wheel openings were also
used. |
