Sorry it took so long, but I now have some pictures for you. Bought swivel base online from discountvantruck. RV is 2003 Winnebago Chalet 31cr. Std E-450 chassis. Did some slight mods to make it fit perfect. Reaming seat holes, raised it 2" and just to be sure I cleared the brand new floor I ground a tiny bit off of a non functional piece of the bracket. At first I was only lukewarm as it was not as easy to swivel as hoped. But now that I have the swivel method figured out, it is easy. Now I am considering buying the drivers side too. It really opens up the interior when parked with the seat swiveled 180. Next the pictures will come...as I figure out how. May take me a few minutes
