I ended up using more force yesterday on levering the hinge but I could only get the holes to within 1cm of each other. It felt achievable but fruitless in the end. I found the easiest roof position for this to be fully open, I struggled with it when the roof was low.The roof struts create forces which are probably acting against what you are trying to do. With additional people try lowering the roof and propping it up internally so that the hinge is just accessible. Using a small ratchet strap put each strut in compression and remove one end.
Hopefully you will then be able to align the hinge with some muscle and grunt.
Thanks for the extra advice. I was hoping to avoid removing the gas struts and will have to figure out how to do that. So you think keep the roof low, elevated evenly at both ends and open enough to get to the hinge is the way to go? Wondering how you lift from the inside with it so low.
Will have to try again another day.
