The windshield frame is wider at the bottom, and the centerline for the four holes to secure the glass is parallel to the front of the frame. Two of those holes are used to mount the blocks.
The result of having the same length for the upper and lower blocks is there is a 1/4" gap between the wind wing glass and the windshield frame at the top, but a 1/4" over-lap at the bottom. If you move the wing inwards; it will strike the frame at the bottom and break.
I found a pic of a original Gulf race car, and zoomed in to see a proper gap all the way down, and the lower block is longer.
I made new lower blocks .510" longer, with the hinge pivot hole .510 longer also.
The result is; it looks and functions like the car in my photo, with a parallel gap.
It would appear that the designer of the after market mounting kits made all four blocks the same length of .970", but maybe should have made the lower blocks 1.480".
If this is true; almost every replica has the issue, no matter what make of replica it is.
Do any of you agree with me?
My car now looks and works much better.

The blocks should be the same size. The front edge of each block is about even with the leading edge of the windshield frame. The screw hole that holds the block to the frame is set back from the leading edge by the same distance. I'm going to take a WAG and say the holes in the frame were drilled incorrectly or one of your blocks is mounted in reverse to the windwing hinge.
