Swivelling Front Seats

I've been tackling the Captain Swivel Seats, we bought two Ford Galaxy seats with integrated swivel plates.  Being Ford seats I am having to modify the mountings to fit the Citroen van. Started by having to weld some additional metal plates to the fixing to fit the Relay seat box mounting holes. For some reason I welded the adapter plates on the wrong way round and then realised they were on the wrong seat!
Packed up, will have another go tomo!
It's taken a few days modifying the two Captain Swivel Seats to fit the seat bases, but it's done now!
