Pool skimmers

Hello,We are fully renovating a concrete in-ground pool from the 70’s.We need to replace both (2) skimmers.  I have attached photos of the old, can you please recommend replacements?  The old have already been cut and jackhammered out.The pool is 28,000 gallon, kidney shape.We will also be looking for a natural gas heater. Suggestions and advice for these items is appreciated,Thanks,Victor Martin
