LOL!!!
I had the same problem areas on my 66!!! Muahahahahaha!!!
But I found a trick, and it may only be applicable to my car...but I'll tell you my secret.
With the headlight bezels... It was a matter of tightening the screws in a particular order.
As for the tail lights... yeah well, I still havn't found the trick to that.
But honestly, I like the pinstripe.
