Last two pics...
I can see that aside from cutting the car's roof top, I'll also have to cut away everything to the tip of the trunk, but the width of the station wagon top in the back is perfect. This may be the determining factor in how much of the front part of the top gets cut, although it will probably sit more flush when I chop it. I'm keeping the entire "bubble" top and will be smoking the glass for tinting, so I know I can't hack into the support part of the top too much. I figure I'll probably have to hack the a-pillars in front a litle bit, but it all depends on how the top sits on the body after it's chopped.
Am I heading in the right direction with this, or is there a better way to accomplish what I'm doing?
