Need Inside Dimensions for E.Williams 18x36 Emerald inground

[shkorme]

I am trying to get the original dimensions or drawings for my 1986 Esther Williams 18x36 inground liner pool. This emerald shaped kit pool was a DIY project for my parents and we are in need of a liner replacement. It is the "large shallow end" option and I would like to find a custom liner that will last as long as the original liner that came with the kit (14 years). Any information will certianly help. Thank you.
