LRDG Chevrolet 1533X2 Aero-screens

[Charlie Down]

Thanks Grant, that was my next question answered!
Do you have any photos/diagrams/dimensions? Also, either I'm being a bit thick, or I'm not quite seeing how they fit differently looking at photos on other postings of wiper motors. Maybe I'm looking at the wrong motors?
I've dug up some photos of the windscreen, which shows the motors fitted after the trucks were further modified with condenser, sand mat racks and stowage chest in the Ammo body, in Egypt prior to issue to the LRDG. However, all the operational photos show them removed from the windscreen. They are all on early issue trucks with no forward MG mounts.
