Ha! Some interesting questions!
The screen has had 3inches taken off it - a local glass merchant did it after just one attempt - after which I had to radius the corners and finish the rest off (with a band-sander of all things!!).
The roof HAS been chopped, I cut the front pillars, raked them backwards and inwards, the B-posts had 2 inch taken out and the rear quarters had a "v" taken out behind the side windows and also split down the middle. The door frames were cut and re-shaped. The whole idea was to keep the basic Capri shape but it did prove a bit difficult especially with the fact that it had a tailgate, which also had to be split. All this allowed me to chop it without having to quarter the roof.
I understand why it looks like I may have just "raked" the roof, I sometimes look at it and wish I had maybe put a bit more thought into it and tried a bit harder to get round the tailgate/hinge problem.
As for the spoiler - it started out as a very rough turbo-tail copy that I cut up and extended and moulded it all into one piece. (The gas-rams DID prove a bit weak though!).
Here's a pic of it next to my other one, which, incidently, also had the suspension lowered by 2 inches.
