Pantera-electronics is Jon Haas.
He just got through with a project building replacement harnesses for Wilikinson.
In that process he had to locate all of the original factory connectors amongst other things.
He has pictures of them posted on the web page.
If you can't find it there, it may not exist.
What I would recommend to you is you take a picture of the connectors that you want and email it to him.
The worst that can happen is he doesn't have it, but I doubt that.
His email address is, jhmotorwerke@gmail.com.
Tell him I sent you.
