Both of the photoshops you have done are excellent. Thanks for posting them! I really like the first one with the chop.
Wise advice, you can chop it anytime, live with it and enjoy it, don't rush it, that car has some beautiful lines just the way it is. As I've suggested on another thread, leave the chop till you get tired of the car, then it'll be new again.
Hard top. If you must see the sky, then a sliding or removeable canvas top cut in as big as possible. If ya went with the faster rear window angle, the canvas top could acutally save a ton of metalwork blending it all together.
