hood question....

[va_tlc]

my friend is building a 72 blazer, he has put new fenders new doors new rear quarters, original hood, well he has done had it painted , and when he finally got the new aftermarket grille, the hood wont close, as he told me the hood has always been about 2 inches higher in the back when closed, but all ya had to do was push the back down and it lines up great, so my question is do yall think he needs new hinges? or could it be something else, thanks for any advise and im gonna get some pics of it and postem for him over on the blazer forum, it did turn out really nice, thanks for any ideas yall have
