Marketplace. Was going to mount seats w slides on top., but decided I wanted swivel too. So cut 7" out & glassed. Now Todd seats on top w short pedestal.
I bought 2 FG boxes and will mount 6" pedestals/seats on top. More for comfort height than space. Those bench seats were made for dwarfs.
Pics coming when I find them
Once you decide on a configuration, buy the most meticulously maintained and repair documented boat. All boats need repairs, but start with as clean a slate as you can afford. One hurdle at a time.
Phelps (soon to be "Green Bananas") has a stripe around bridge. Painting, have to decide soon whether to replace it or not. Whaddya think ? Don't see many with stripe, but might look naked w/o one ?
Friend had a 43 Bike w 892's. Was a dealer for some brand of big 6 cyl inlines. Boatyard cut the side out of the boat to do it. Beautiful job when done.

From bitter experience, crawl under the transom or get a mirror & look at what is inside. Moving your plan a couple inches may make a job easier.
And, a scrap boat with one & a sawzall would be a home run in my book. Check local marinas
It ain't pretty but I won using oak semi circles. Not looking for longevity.
Guy wanted to sell me Trex decking on my house. I said why? I'm 78........
