Running late, very late, but maybe there is still hope.
I had to remove the roof from the fighting compartment since it was sitting too high. The edges of the sides are bevelled and just like the edges of the roof BUT the edges of the roof were not bevelled all the way up to the top surface. The bevelled part of the edge was only half the thickness of the roof which left a visible edge to the roof, the roof was almost 1 millimetre too high which meant that the "windshield" didn't reach all the way from the roof down to the top of the "hood".
First I thought that the "windshield" was too narrow but after finding some images on the internet I realised that the roof had to fixed. Some damages to the walls but on the whole the "surgery" was mostly successful. Fixing the roof before gluing it in place would have been a lot easier .....
Some of the repairs with strips of white styrene may be visible in the images below. The remaining work now is some small parts, I will use some of the photoetch and then painting. All grey, haven't got time for camouflage patterns

If I manage to get it finished I just need to figure out how to add images to the campaign gallery .....
