Thanks for the video Fieldsken, that actually looks pretty handy.
I'm with some of the other guys that like to open the hood all of the way back and rest it on the roof for full access.
I've been thinking about making a magnetic "hood stop" for this scenario, it would magnetically attach to the window frame area under the roof, and have a bumper stop that stuck out in front of the roof to protect the roof and hood. Of course it wouldn't be as nice as this setup because you'd have to take it off and on, but it would allow the hood to fully open when you were working on your '40 in the garage...
