I fear necessity caused the retro fit of those ugly hooks.

Early cab 11 did not have them and when installed they used existing holes for the cowl screws and substituted the hooks eyelets in place of the screw. A lot of the cab 12 I have seen had new/extra holes drilled in the cowl facing. They were not very elegant.

I have not yet installed the insulation inside the engine cover and can tell you the sheet on the passengerf side get hot enough to burn knee caps if you are wearing short pants.

A number of early parade ground photos in Canada shows the driver's door wide open and resting on the cargo box...... eventually all cab 12 and retro on cab 11 a canvass restraining strap was installed that prevent the door from opening more than some 90 degree..... maybe that's when they started using the ugly door hooks

Cheers
