That starter does not have a "solenoid". What are you working on that you're calling one? If you're referring to the push button on top of the starter, that's just a simple switch. The starter drive gear is engaged mechanically, not by solenoid action. try this- - - -super-glue a nickel or a flat washer on top of the switch button. It looks like the foot pedal linkage is not pushing the button down far enough to engage the contacts and make the starter motor turn.
If that trick makes the starter turn, then fix the worn spots on the pedal linkage- - - - -there are several places where holes can elongate or rod ends can wear undersize. There are no adjustments.

Sorry for my mistake in terminology. I have a switch (from the foot starter). Apologies for the confusion. Jerry i'll try your idea today wit the flat washer. I did previously use a paint stirrer to bridge that gap, I've also pushed that button in manually as hard as I can to no avail.
Maybe someone here can help explain this to me, if in a bench test with the starter switch removed, direct battery to contact on the starter motor, and it spins up. Why would that not be replicated once installed in the truck? I used leads to hook up in almost the exact same way, except for grounding which I tried in multiple places, and it doesn't change anything. I did do a bench test with the starter switch in place too, and that also spun up when I compressed the button. I recognize i'm lacking the mechanical understanding here, but i'd have thought that in repeated scenarios (ie- same set up for power) and the only difference is it's bolted in the truck, that you'd get at least some semblance of the motor turning over.
