I'm looking for suggestions regarding the replacement of these failing hatch handle seats. Several of them are cracking in various places. Rig-Rite has them in cast aluminum which is nice, part# Goi HT-HSC. Unfortunately, they are quoted at $80 USD per piece ($640 USD to replace all of them!). There's got to be a less expensive option out there. Is anyone else looking to replace these parts? Has anyone already found a good solution or source?
