Evolution E2 question

[shanks]

This is my first post here. I just picked up a used (4 times) E2 for a great deal and used it this past weekend for the first time. When I popped it up I noticed a problem that either wasn't there or I didn't see when I purchased it. On one of the slide outs, where the top attaches to the hard top there is a plastic rail that the canvas attaches to. The rail is then screwed into the hard top. All of the screws were pulled out of the particle board. I looked and looked and couldn't get access to the heads of the screw to reattach the rail to the top. Has anyone had this problem? What is the best way to reattach the rail?

Thanks in advance.
