This is comming along sweet. It is going to be so nice just to copy what you have done and not have to think about it for once
As far as our vintage hinge I do not think it will work because ours are tuckers and you need one to lift out and around. By tuckers what I mean is when you open the door the leading edge tuckes in behind the fender. For a rear hatch you will need a lift out and up style. I think the ones you linked to would work great and it sure was nice of them to post all those close up shots to help to build your own. Keep it up great work as always.
Whern you get ready for your hood mod let me help with the thinking part!
