I stuck the two halves together then made some floor sections of the right shape fixing them inside to brace the sides. I cut glazing strips from a perspex shirt collar stiffening strip which comes with most new shirts, I stuck these in with superglue.

The cab rear panels are not correct as it is possible to see right through the prototype but they added rigidity and don't forget that this was just for a photoshoot so detail wasn't too important. Next I traced around the body and made a template for the roof which I made from Balsa wood? The first layer was 2mm thick and smaller than the template by 1.5mm to fit inside the body sides the 2nd layer was 6mm thick and the same size as the template. These were glued together and left to cure. I shaped and contoured the roof, sanding it first with course and then fine sandpaper, I coated the whole thing with a couple of thick coats of grey acrylic primer to harden it up.

As you can see it wasn't a perfect fit but never mind eh!!
