WOW!!! Thanks so much.
1. I kinda thought that the "protector" was some type of insulator. Funny that it wasn't on the original or the 1st replacement. Maybe that is what was causing the problem since the one I was replacing did not have the insulator ring.
2. I didn't even think about moving the contact pin. Wow!! feeling stupid about now.

Next crazy question is should I use the old spring or the new spring.
3. Yes, the compression spring is in place.
4. Yes, locking place is being installed correctly. Trust me, out of frustration I tried to see if it could be installed the other way. It cannot!
5. Will try pressing the c-cam. That spring is so strong, I don't want to break the c-cam.
Thank you so much for the pictures and taking the time to explain things. I will update at a later date.
