Richard,
Dusty53's reference provided is the link to the whole manual. If you click his link, then click on the
6-53 next to the word "Clutch" that gets you closer to the correct page.
The actual page in that manual with a kinda fuzzy picture of the truck clutch release linkage is on
Page 6-57. See Figure# 121 and the short adjustment instruction above the picture (screenshot provided below).
A better picture of the clutch release linkage is found in
Figure 115 in the 1941 Shop Manual from the same resource site as Dusty53's reference (2nd screenshot provided below).
Both manuals have almost the same picture and parts configuration, so it should provide you (hopefully) what you need to solve the problem. NOTE: The only real difference is the change from '41 to '42-'47 with the earlier "adjustment nut" that was pushing the clutch release arm away from the clutch pedal, changed to a "jamb" nut in the '42-'47 configuration (adjuster nut with a stop nut to retain the adjustment setting) which then leaves more threads on the connecting link to adjust it's length for clutch pedal free travel setting.
Let us know what you figure out and ask more questions if still not enough info.
Dan
