Welp I figured it out! Where the solenoid grounds is bad. Just have to run a ground wire to the main ground/exhaust manifold. Once I did that the solenoid clicked. Starter didn’t crank but I have a spare.

Thanks again, everyone!
Test and make sure starter power is coming out of the solenoid when the "click" sounds.

For those wondering: it’s running! The new solenoid ended up being stuck on. I threw the old/original one back on. Worked fine. The starter was wasted, so I threw a new one on. She cranked to life after like 15 years!

All that to find out the solenoid ground was toast.
