The windscreen rake is just one of the problems I have been wrestling with on my 275GTB/Z3 project (
http://www.madabout-kitcars.com/foru...?t=5207&page=4). Basically, the Z3 is a different shape - shorter nose, longer doors, higher side window (and different shape), more room between the door and the rear wheel, wider roof, bigger boot lid ... As the old saying has it "If I were going there I wouldn't start from here". Tribute have done an amazing job of producing a nicely cohesive design and on my own I can not match their skill or speed of working but "I have started so I will continue".
