I like the idea of a center hinge in the hood as well, in my case I need to have a center hood scoop for the V6 and that makes that option impractical for me.
So from what I gather so far is that it is not a big issue lifting the hood off.
I can also see that as I am lifting mine off the car while it is up off the ground 2 feet, and then being a height challenged fellow
or in my day a fellow of short stature and clamshell fenders on the car to boot might make it seem more difficult than it really is.
"I don't think a rear hinge would work well. The scuttle is (generally) curved, so a piano hinge wouldn't fly. You probably don't want a pair of external hinges sticking out...though you certainly could do that. "One of my regrets as I made my scuttle flat across the top, I should have made it with a gentle curve, it would have made fitting the hood a little easier I think. I was thinking of some nice chrome hinges off a Healy or something, rather than standard style hinges.
Basically it seems like I am better off just doing a wait and see, if it isn't a problem, do nothing and if it is, look at the hinges perhaps as an option.
