Hi Moon,
I have thought about this for some time, I wouldn't have called it a hearse, I would have rather called it an FC Nomad. I think that this picture is better than what Harko was trying to achieve in his "Cut it custom 2 door wagon" project.
http://fefcholden.org.au/forum/index.php/topic,4554.0.htmlThe long piece of glass would be the biggest issue, as well as the structual strength with not much roof support.
Don't you just love photoshop!
You are able to see what the desired result would be
before you start.
All the same, well done, now as Custom FC has said, the only thing to do is build it, keep us all posted on your progress.
