In search of unobtainable bottom tracks!!!

My husband and I just aquired our neighbors pool. Long story short, our neighbor threw out most of the bottom tracs on accident. The pool is an Atlantic J2000 or Malibu and the part no. is **1460034.**We CANNOT FIND these available ANYWHERE!!! Is there any advice on how to make a different track work ? or does anyone have these tracks and doesn’t need them anymore?
