Seat
The drivers side seat up next, theres less room to work due to the steering column & since the passenger seat is already in place.
The front edge is same as before - sliding the seat runners at fully forward (seat fully back position) - positioning the seat against the back panel and marking the position of the front holes on the floor:
I then drilled the front positions with a 4mm pilot hole and lined up my template, taken from the underside of the seat, to locate the position of the rear holes. Those two M4 bolts in the front holes are just to line everything up:
The mounting bolts are M8, rear bolts dropped in fine, the front holes needed opening up a touch to let the seat rotate on the back bolts and let the front bolts drop into place:
This was a much better method than the passenger seat!

The result - both seats & belts now installed:
