I visited my good friend Wayne Omura today. He has the same giant hollowing system as me. He has the original Frank Sudol rig. When I told him that I wanted to add a rig for a webcam, he pulled just what I need from one of his many drawers around his shop. Problem is, he can't remember where he got it, or even the name of it. A search with Google lens gives me lots of hits. A website balluff.com has one, but it's impossible to find the right size. I will call them tomorrow. The bar is one inch and a half. The other one is 3/4 in. Then I need another one with 2 3/4 in holes. Wayne just called, he thinks he got it from J W Winco. Again, Impossible to find what you need there. I'm open to suggestions for other sites. Google gave me some good sites, one Checkoslovakia and the other one in Turkey. I think the shipping might be a bit too much from there, LOL I'll attach a picture of the main part below. Both are the same just different sizes.
