Hi All,
I have answered most of my questions but just a few I have posted today in my quest to replace my liner. My question here is how does the step gasket works and where do i get the rail pieces? Mine is 7' 11" by 35.5". You can see mine in the picture below. I Assume I should replace it with the new liner just for aesthetics, but what is happening between the liner and the piece I have pictured below? Does something go under the liner as well? Between the liner and the wall? Maybe a better question is, "what are each of the layers starting with the wall through the liner and this rail on top?"
