I wish Terry, it turns out to be an Aguti swivel base which has a fully enclosed single fixing which controls the swivel and is non-servicable.
I'm expecting a ££££££££ quote as its German and not a stock item, none in the UK.
The problem was identified when it was in for MOT and service. The passenger seat rocks quite badly when in swivel mode, especially when fully forward or back on the frame and it is getting worse.
David, I will certainly look at an OEM replacement before lashing out £££. I had a brief look at the CTO swivel bases, the recommended Ducato version has the correct overall dimensions and the front bolt locations are spot on but the rear fixing point is different. That may be as simple as drilling a new locator hole in the CTO frame ......... but I'll need to check that out. I expect that will certainly be a lot cheaper than the Aguti replacement assuming Carthago can supply one. Aguti don't deal with private individuals so I have to go through Carthago
