Door weatherstrip interference

I posted this issue in my quarter window install thread but wanted to give it is own thread to get more eyeballs on it.  Car is a 1976 280z.

I just installed my quarter windows and I'm having a bit of interference with the weatherstrip on the top of the door and the vertical weatherstrip on the front of the quarter window.  All the weatherstripping is brand new from Precision.   How did this work from the factory? Was there interference?   Looks like I should probably trim the quarter window weatherstrip back to provide clearance for the door weatherstrip.  Any other thoughts?
