Three box side versions.

6 foot, 8 foot -and - 9 foot but only with the 300 series for the latter.


The 122" wheelbase Utiline trucks had a 7.5' bed. The late 65-71 trucks had a 128" wheelbase and the 72-85 trucks had a 131" wheelbase. Did the 72-85 trucks use the same bed sides as the 65-71 trucks? What method was used to make up the 3" difference in wheelbase? The OP mentioned something about flat fender trucks. These may have used a completely different bed side and I have no idea what the wheelbase is on these.
