Chain plate/rod on hunter legend 37.5/40.5

[bensolomon]

I hope everyone is well. Does anybody know the best way to inspect the chain plate attachment of the rod on a Hunter legend 37.5/40.5? On my boat, the shrouds are connected through the deck to a solid rod that then attaches to a point on the bottom of the boat that is sealed inside a fiberglass box that looks structural. I am hesitant to cut an inspection port.

Thank you,
Ben
