Nice looking truck. I'll add a couple thoughts to what others have already said.
There are threaded adjusters on the shift rods, you can adjust them out to move the shift lever up. You would need to adjust both the same so that neutral is in the same place for the R-1 and the 2-3 shifts for the lever at the top of the steering column.
Wear has a big effect on shift lever movement. There are bushings at both ends of the shift rods that wear, the ends of the shift rods wear, and the mechanism at the bottom of the steering column can wear. Ross (ALBUQ F-1) did a great write up a while back on getting this stuff back to new.
