I've been studying my side doors on my '88 trying to figure out how to make them into a gulwing. Basically, I need to figure out how to fuse them together so that the doors are light enough to be practical to hinge from the top and not crack at the vertical weld between the doors or try to fold in half while pulling it down.
I'd also like to see how Matchstick's kit mounts the hinges. Hopefully the hinges get installed in a way that they can be adjusted in at least two directions to get the gaps right.
