Does anyone recognise these seat runners?

Cheers for that Ginge, After finding the seats I had a look through the IVA manual and it says if the seats are adjustable (back and forth) then the headrest needs to be attached to the seat so that it will move with the seat. Otherwise it can be attached to the rollbar.

My plan is to fab up a system to attach the headrest to the seat, as I know i'll be wanting adjustable seats so that other people can drive the car.
