Next the locking swivel went on. The LSV has a sloped fiberglass mount to tip the seat back for your driving pleasure, I would encourage not to mess with your driving pleasure, after all, that's the point of having a boat like this right?? The nylon spacers worked well for this application - 1) they will not rust/corrode/incur galvanic action, 2) they are very easy to modify to shape. The 1/4-20x0.75" hardware was used on the front two mount holes and the longer 1.5" with two spacers on each side were used in the rear two mounting holes. The top spacer on each side was ground to an angle to match the mating swivel plate. (see next two pictures). I used Nyloc nuts here simply because I didn't want vibrations to loosen over time, especially the front two bolts since the slide and swivel do not meet flat together and space was at a premium to not interfere with the slide mechanism.

Now the fun part. Pick the heavy floor back up, lift into the boat, and reinstall without damaging precious vinyl. Have I mentioned yet that the floor is heavy? Once the floor was in place again, I switched to mounting the aluminum plate to the bottom of the seat. I was sweating the detail of whether or not the seat would be able to swivel without hitting the outside starboard wall, well actually I was sweating from the 97* NC heat, but concerned about the space requirement too.
The seat plate was pretty straight forward, I re drilled the two front seat holes about 1-1.5" further aft to fit the 12"x12" plate, plenty of stock in the seat to do that. Four 5/16" bolts, larger fender washers to distribute load, lock washers, and nuts - you get the idea. At this point, referencing how everything was mounted before, I assumed the seat would have to move towards the center line of the boat if it had to go anywhere, so I offset the aluminum plate towards the starboard side thus giving me more maneuvering room later in the assembly process.

Now, back to sweating... the position of the seat on the swivel. Yeah OK, the NC heat too. I basically lifted the seat into position and tested it at 0* and 90* and once I was happy, traced the outline of the swivel on the aluminum plate. Here is the finished product, minus the seat.
