Having troubles helping my neighbours find a 36x16 liner , so we’re thinking of taking 4 feet off to turn it into a 32x16 to a more popular size. The only set back I think would be the metal wall joining system, . This one has the hidden joint where you use a bar on the back side and use a hammer to hit down on it to keep them pinched together. Other than that , it would seem you just need to take out a set of the side braces and pull the end in closer. Possible to pull this off ? Thanks for any ideas.
