21 foot heritage pool parts

I’m looking for the top rail to  hold the liner in my pool.  It is a 21 foot round heritage pool.  I also need the rubber gaskets that go with it.  I have 5 good ones, but i believe it takes 14 for installation.  I also need one of the composite feet for one of the uprights.  Do you have any of the parts available?

We’d be glad to assist you. Is your pool 52" or 54" tall? Does it have steel or resin top rails?
