While replacing the liner in an 18'x33' oval pool, a storm blew through and knocked in the pool. Upon inspection after the storm, we found that the bottom plates on the vertical uprights that attach to the track for the walls have corroded. Is there any way to replace these? Two posts came down, but I would assume the rest are also in bad shape. This is a "Leisure King" pool with a 25 year warranty. We are 18 years into the warranty, but cannot find the manufacturer and the original dealer where the pool was purchased is no longer in business. The local businesses here don't seem too interested in helping - other than selling a new pool kit.
