Thanks for all of the feedback, guys.
Since the centerline for the four holes to secure the windshield is parallel to the front face of the windshield bracket, yet the bracket is much wider at the bottom; the lower blocks need to be longer to position the two hinge points for each wing parallel to the inside edge. The windshield frame is wider at the bottom when viewed from the side of the car.
Given what was found on Fatboy's Kirkham, and my photo of the original Gulf race car; I firmly believe that the original cars must have had longer lower blocks.
I say this because the wings were an after thought and therefore they used two of the four holes which were originally intended to secure the windshield. So; they couldn't and didn't move the lower hole towards the interior of the car to create the parallel gap for the wings. They probably just made the lower block longer. Sorry for the long winded explanation. Either way; I am much happier with the appearance and the function of the glass wings now that I have a 1/4" gap between the wing and the frame from top to bottom.

Thanks to all.
