If and when you go ahead with it, take lots of pics! I sure wanna see how you go about it. What is your plan so far? I think most guys cut out around the back glass and lay it in at a lower angle, making a few pie cuts to compensate. I think filler strips will be needed as the roof will shift further foward when the A pillars are cut.
Do you plan on moving, angling or removing the B pillars?
Let me know, because that is a style car I would really love to own someday. Those cars look SO SWEET chopped!
