You don't want to do the jump seat box? Figured since you were going to do a pedestal, a single seat would work out.

I still want to do a B2B seat that can go over the removable pedestal, I was hoping to find one that unfolds but if not then two regular seats placed B2B will work.
I finished sanding all the floor pieces and ordered and received the removable pedestal mount for the passenger side, I went with the Attwood 238. I spent a few days trying to figure out mounting locations for the future B2B seat and finally decided to just put the backing plates in the right places to accommodate a normal size B2B base (31.25x13.5" seemed to be standard). I will install 6 t-nuts in those plates and will just have to modify whatever seat base I eventually get to hit those locations (or build my own out of wood, then I can put the mounting locations right where the t-nuts are located). With that decision made I glued on the first layer of 1/2" backing plates.
My Shark Grey Nautolex and SS t-nuts arrived, and I was surprised to see a the colors had a brown tinge instead of the grey I expected. At first I thought they sent the wrong kind, but it appears I was victim of the low-res picture on their site, when I searched for a better picture the color is the same as I received. It's not too far off and will work fine, just not what I though was coming. Now that I have the t-nuts I will be drilling the bolt mounting holes tomorrow and installing the nuts, then gluing on the second backer plates over top, which will give me a full 1.5" thickness for all seat mounts. After that I will be sealing with OTF for the foreseeable future, 3 coats per side per floor piece and then another 3 coats of spar will take a while to apply.
