Although the rear "hatch" serves no purpose I wanted to keep it accessible for maintenance issues so I fixed 2 x 10m treaded bolts to the rear of the chassis.
.
I stuck some masking tape inside the rear hatch cover roughly where the bolt should protrude.
.
I then held the hatch firmly in the appropriate position so the bolt ends would leave a mark on the masking tape showing where to drill the holes.
Holes drilled I put a pair of holding nuts on the inside so the hatch would rest against them and a pair of external nuts fixing the hatch in place.
With a little adjustment it should fit reasonably well, the holding nuts will disappear under or around the rear number plate but it can be remove easily for access.
