Is windshield trim necessary?

My '67 valiant is running with stock gaskets and no trim. it looks a bit unfinished from close up but from just a short distance is no problem, it does not leak. I'll try to post a pic close up but the car is in the members gallery without a close up if you'd like to take a look.
I think you'll be just fine.
By the way, at car shows no one has commented about that... and you know how some people are at car shows.
