Brian, I did this on my ‘52 and ran into the same problem. In my opinion and obviously yours, they need to float in order to move with the rod. I squished in the first one only to find it didn’t move so I figured it would prematurely wear out the felt. It was jammed in there so tight, I didn’t dare to remove it fearing I would have destroyed it. I still need to replace sections of the floor, so I figured I would replace it at that time. I compared it with the original and it was way too thick. I used a utility knife to thin the second one down so it would be snug but still move. Seems like that did the trick.
Good Luck!
