Great to hear of yet another 1975 18SF. I have mine wide open right now and just crawled out of the bilge. The box stringers are 26.5" apart which corresponds more or less to the coffin box and also the first set of steps from the keel. My stringers (which I am in the process of rebuilding) are 3/4 - 1" below the liner sitting on plywood and Potter Putty. If you want to be safe, you might drill oversized through skin and 1/2" plywood core and fill with thickened epoxy. My lean post landed with one screw on the cover of the livewell which I have also removed. Happy to send pictures.

Thanks for the reply! Are the pictures looking forward or towards the stern? It looks like I can drill through the skin and the plywood (if the plywood is there) but NOT the stringer and the foam. So I will drill down about 1 to 1.5". If their is no plywood there then I might be able to use toggle screws for some added support and of course I would fill with west systems. Thoughts?

These pics are looking forward. If the deck coring is still good, you can screw right into the deck. It's approximately 1/4"of glass, 3/8"+ plywood coring and another skin of glass on the underside yielding about 3/4" of substrate. There may or may not be enough room to use toggle bolts, (I'm thinking not). I would 5200 it down as well, unless you're going to do other work later which would require removing it. If I hadn't raised my deck, I wouldn't have a problem screwing through the deck into the top of the stringer. Good luck!
