Thanks to all. I will try the contact cement and let you know.
I fear though I need an adjustment to the slide as when closed the slide floor is about an inch or more above the inside floor and doesn't seem completely level to me. That is unlike new ones I have seen at dealerships. Their gaps are much tighter and level.
So I'll try the contact cement and let it dry good and see if it tears it up again when I close it.
So if that turns out to be it, is that something you can do yourself or is that a dealer only thing?
Again thanks.
