After sizing this Z411 frame via John Costella's recommendation and then scaling mine at 89% along with a 2 degree ccw rotation and pin-cushion correction of -7.0(Photoshop), this is the comparison result:
Forget what I said about your's being 1/6th. I was kinda jumping the gun with something I was thinking myself about the frame size being. Sorta answering it myself.

Notice how the 3 tallest pyracantha bushes match where: 1) the lampost at the end of the wall 2) in the walls end area where BDM and anybody else might have been 3) the tree next to the Turnpike sign. Which would mean the car was painted in larger than normal. Where the wall should be. Camouflaging the wall/Its contents.
Also, notice how the FBI recreation, real life Turnpike sign, it fits almost exactly into a space between the dark Presidential flag and tree in the Z film. To mee, it's like a painted scene. A cover-up.
Those Z-film pyracantha bushes are unrealistic, they were NOT that height on the day of the assassination.
As this FBI recreation 5 days later shows.
Interested to know what you think. Chris. I've found some other interesting thing's which I'll post.
