When attempting to start the vehicle there is a metal-to-metal grinding sound?

Listen when I try to start it, what is happening? Horrible sounds like metal-to-metal grinding against each other in a bad way.

New (used) motor, new starter, brand new torque converter, had the transmission rebuilt, new power steering pump, now this...

Yep, the starter motor is no good, can I ask where you are getting the starter from? I would use an AC Delco unit. Thanks for the video.

Here is how to change the starter out:

Starter is brand new not rebuilt straight from O'Reilly's auto parts. Which is who also gave me the wrong one to begin with.

Okay, did that, same thing, but check this out; if I disconnect the distributor, it cranks fine no problem. Soon as I plug in the distributor it goes back to that same sound.

I would double check the firing order, here is a diagram to help you. Also, it could be the distributor cap or rotor, I would replace them if they show signs of wear. Check out the images (below). Please let us know what happens.
