The Cabin door on my 330SS at times is very hard to close, anyone have any tips how to remedy?

One of the sliders bolted to the bottom of mine came off. REALLY hard to get the door closed. When the door is open look between the door and the bulkhead and see if yours is missing too. 2 minutes to fix once you get to it but I think we am going to have to pull the foot rest to get to the slider. If anyone knows for sure please let me know.
