We have received the following advice from one customer, unfortunately I am not sure which transit variant it relates to but perhaps it will make sense in your own van: the swivel lines up perfectly with the floor fixings, the only thing that the installer needs to do is, under the rear off side swivel floor fixing point runs a 1cm high and wide ridge in the transit floor pressing which needs to panel beaten down so that the swivel sits flush to the floor ).
Will the swivel fit other models of the Ford Transit?The swivel appears to not fit in Mark 4 vans (before 2006) or earlier due to different floor fixing locations.
The new Transit Custom (2013+) is not suitable for this swivel. We have tried a number of times to develop a swivel for the new van model but with no success to date. At the moment we are taking a break from trying to solve the problem.
