Fastback fold down seat not folding down

I have a 69 FB, and last year the back seat would not fold down. I could see that when the lever on the back side of the was pulled all the way, one of the cams was not moving enough to disengage from the post. I took the back seat out and laid it on my workbench back side up. As I moved the lever. I could see what was happening. Both of the cams were missing one of the two set screws, and on one side, the remaining one was loose. It only took a few minutes to fix. That may not be what you have going on, bot take another look at your pictures, and compare carefully to what you have now. If the seat was working before, There is probably a 90% chance that you have done something wrong. If I remember right, the cams can be put in wrong which would make them stick out too much. Please post pictures.
