Hobie 18 shroud anchor plates

Will the Hobie 18 shroud anchor reinforcement plate kit fit my gcat 5.7?
I think I answered my own question. Looks like they’re too wide to fit the deck lip. Looking to reinforce the shroud anchors on my Gcat 5.7
Are you sure they don't fit? I have a couple and can measure them if you are not sure.

The H18 anchor plares are curved (inboard/outboard) to fit in a dished out recess in the side of the hull. Unless your G cat has a similar dished out recess (I would be very surprised if it did), the H18 plate isn’t going to sit flat.

Thanks for the help, both of you. Considering I use to own an 18 I should have known better. I can tell from photos it’s a dead deal.
I have a set of these that I bought for my G-Cat 5.7 about 10 years ago. They are still in the package used because they did not fit.
