If the passeger side is perfect,look at the bumper adjustment at the back of the hood,there should be a adjustable bumper at the corner. try adjusting that, Sometimes they are old and brittle if they have not been replaced, there should also be rubber bumpers along the fender were is is bolted to the inner fender.Just check the usual spots, some of these bumpers may be raised up to high...not seating correctly. If that does not work,take the bolts out of the hinge (unhook) the hinge from the fire wall and close the hood..see if it flushes out, sometimes there is some play were the hinge will move down lower on the fire wall to lower the hood flush.See what happens and update your post.
