Mike,
That's great, I'm a bit out overall in length and the profile is too shallow around the wing nut area. I'll adjust and re-post new drawings later.

Here is my final drawing of the Aeroscreen and the Hinge Brackets.
Thanks to Mike Kelly for the photos and dimensions.

Thread
 

The thread in the hinge clamp appears to be 5/16" probably BSW

Thanks Mike,
I've edited the drawing accordingly.

Windshield support or throwout arms
 

I've just put up a thread on the support arms mentioned in posts #4 to 6.
"CMP windshield throwout arm assemblies" at http://www.mapleleafup.net/forums/sh...884#post280884

I made it a separate thread as people may want to add content related to CMP as well the 1533x2

Chevrolet 1533X2 windscreen
 

Grant, I've duplicated this piece on your post as it's relevant to both. Hope that's ok.
Looking at the reference photos most of the arm components of the 1533X2 are at least similar, if not identical to the CMP versions. The arm itself looks like the short arm, with the upper bracket and the hand wheel clamps looking the same as the CMP equivalents.
The arm length scales out at roughly 192mm/7-1/2" which corresponds closely with your measurements above.
The bottom main hinge looks like a piano hinge.
I am mid way through drawing the windscreen, but could do with some help with the following:

Wiper arms
Dimensions of the hand wheel clamps, and photos of both sides.
Photos of the hand wheel bracket on the side of the windscreen, plus dimensions.
Wiper motor photos and dimensions.

In the last photo of an operational truck you can see the motor has been removed, leaving a spaced mounting bracket. Does anyone have any information about this bracket? In post 3 there's a similar bracket visible on a photo, but the 1533X2 bracket looks like it has a lip on the lower edge.
Also of interest is the factory photo of the truck which has a different lower windscreen bracket compared to the much more robust looking brackets of 'later' operational truck. This is the only photo I have seen of this 'early' bracket. This may just be photo distortion, but it does look narrower than the other bracket.

Here's my initial drawing of the front view of the windscreen and components, without wipers as on operations. Some details still to be added.
Need more information /dimensions and photos of wiper motor, wiper motor mounting brackets, and wipers to do rear and side view of windscreen.

Spent a lot of time getting the side arm curves right.

Feedback welcome.

Trico wiper motor
 

On the thread below about throw arms on CMP trucks

http://www.mapleleafup.net/forums/sh...t=32655&page=2

The Trico S-609 in left and right hand setups has been identified as the most likely motor on this windscreen. Alternatively it could be the S-548 model which just had a longer spindle for the wiper arm.
To complete my research and allow me to finish my drawings, all I need now are some dimensions of the motor and mount.
I've attached a rough sketch to show the dimensions in question, from which I should be able to scale the rest.
Any help would be greatly appreciated and drawing posted when complete.
I presume (which is always dangerous!) that the main dimensions will be similar throughout the different models, with only details like mountings and spindles varying depending on model.
Any more photo's would also be helpful.
