V-20 Seat pedestal size

[shaneburris74]

I like the step thing...think it would be a possibility to mount a seat on. Although if I don't want to go with that what size pedestal will I need for factory height seats.
Also, the foam thing scares me if they can absorb water. Thats not good at all. Did they all absorb water right from the start or did something have to occur to cause it..ie. gas soaked, scarred badly etc. Its scary cause this hull I have was sitting uncoverd for a very long time.
