Ok Darryl, I've got the windshield armour out and still have all my fingers and toes so here are some measurements. More to follow as I work out exactly what you want.
All references are assuming the armour is standing upright on its lower edge.
This piece of armour is thicker than that used on most of the hull being 1/2 " thick or possibly a few thousandths of an inch less.
Basic dimensions are 13-1/4 " top to bottom.
62-7/8 " across the top.
60 " across lower edge.
Top edge is square. Lower edge is beveled at an angle of 55 degrees inclusive. i.e. 35 degrees from square with the 'chisel' edge on the front face.
Distance between view ports, from the nearest edge of one to the nearest edge of the other 32". View ports as stated are 8" X 3-1/2".
Wiper slots are 1/2" wide X 1" top to bottom. This puts the centre of the radius at 3/4" up from the lower edge of the visor as the top of the slot is radiused. (1/4" radii).
The wiper slot is also counter bored on the rear face with a square ended tool 7/8" diameter to a depth of .230". This is a circular counter bore only and uses the same centre point as the upper radius, the step is not milled down to the end of the slot.
Distance of wiper slots centre to centre is 34-1/2". They are NOT centred below the view ports.
More to come
