have you tried moving the hinges up on the firewall? sounds like the hinge pivot point is off compared to stock. curious if that would fix it except the hood would be too high.
first, do the doors fit the openings on the rear edge? did you have to add to the rear edge of the doors?
next do the fenders fit the doors on their rear edge? did you have to add there?
just trying to figure out why the hood needed extra length. it could be a few small things that add up. if the fenders ended up too far forward due to additions in other places behind them, then that would explain why the hood needed extra length. do you still have the stock hinges for a test to see if the new hinges are outta whack? know anybody nearby who could lend you a set, or maybe a hood just for test fitting?
