Hello my skimmer (pre 2003) on my above ground pool had a freezing issue over the winter & the bottom dropped out. It was a wide-mouth, but all the replacements I've seen might fit the hole, but none of the screw configurations match at all. No part number is visible, but it may be an old Hercules or Hayward skimmer.

Can I use a newer one & drill new holes, or is there a place to buy old obsolete skimmers?
