Yo! Getting mine inspected here soon . 1969 Columbia 26 . They’re hella rusted and might need to be replaced soon.

Just removed my keel bolts from my 1970s Mark 2 and they appear to be in good shape. my concern was that my metal plate was corroded which I wanted to replace.

Any idea what's in the bottom of the hole and if there is a proper way to reassemble and if any torquer specs?
