Just wanted to updated this wanted thread in case anyone else is searching for old sunroof parts for these 80s vehicles.
From various other threads around the net I figured out to call the Sunroof Doctor @ 417-788-2707.
He's a great and helpful guy who unfortunately couldn't help me with parts, but he then recommended I call Jake Kelley @ 888-298-8140. Jake is an older guy who apparently bought out a lot of parts from ASC back in the day and has been in the business for a LONG time. He now lives in Florida.
I described my issues to Jake and supplied a few pics of my stuff and he knew immediately what I had and exactly what I needed.
Here's a shot of the switch, new harness, service manual, sunroof seal, and he pointed me to what else I still need from Home Depot since parts don't exist for some things.
