Hi Guys
Its been a long time but we've been busy.
Anyway an update on the rotating seats.
I contacted several suppliers but to be honest couldn't justify the prices being asked for the bases plus none were prepared to offer any sort of guarantee they would either fit or work. The UK importer wanted $1000 for a pair plus payment upfront and up to 3 months delivery.
Someone in the UK sent me an Ebay link of a company selling just the swivel plates for $75 so I bought one with a view to fitting myself as I have access to a workshop. I stripped out the seats and fitted it myself with just a few simple mods to enable the swivel to fit between the seat and the base. It works well swivels 180 degrees and has only added inch and half to the height. (see pic below)
Will see how I get on with it and may do the drivers seat as well can't use it at the moment as we've been snowed in for 3 weeks with more snow to come.
