Air pedestals for seats

[bubblerboy64]

I am finishing up my more major projects on "The Big Napper". I did
replace the captains chairs and I think I would like to put air
pedestals in the coach. This bus has the round pipes under the
chairs and I assume they are welded (not bolted) in place. Space is
pretty tight around the dog house and I am looking for direction as
to what air pedestal to use and how to go about this. It would be
nice not to have to cut out the existing supports but I am assuming
that would be the first thing needed. Any info appreciated.
