That’s more or less correct. I don’t recall how it was secured into the aluminum- I’ll be at the boat later today. As far as I could tell the deck is solid glass in that area and as far as I remember the bolts were not fastened to the plate. (Though my Memory isn’t what it was.). Doesn’t matter, work at it slowly and thoughtfully and it will reveal itself. Unless it was glued together….
