5th wheel covers stuck

[tex68w]

I have the factory 5th wheel kit which has plastic spin off covers for the ball and chain hookups but I can't for the life of me get them to release once twisted counter clockwise to be removed. Is this a common issue and if so are there better aftermarket options?

Maybe once you get them out, sand around the outside edge of the cap you twist out.

I finally got them out and cleaned them up. I then marked them with a paint pen so that you can index where they need to be turned to in order to get them out. Initially it required a set of vice grips to remove them, lots of friction causing them to stick due to 11K miles of dust/dirt/grime.
