I finally started gutting the Kona ! After removing the carpet and plywood where the front seats was I noticed what I would call gussets

there is three on each side coming off the stringers. The one in the middle looks as if it has a 1 x on each side and then filled with some kind of epoxy. My question is are these original to the boat or been added. Basicly not sure what to do with these, thought of cutting them out and glassing in new one's

Maybe Frankloc will chime in since he just rebuilt his Kona.
