It attaches with a '32 3-window glove box hinge and a spring steel hinge pin into two tabs on the lower edge of the dash.

Bringing this back up with pics of a 3 window dash in my Vicky. Replacing oval with a 34 Buick instrument panel
Hey dug Where did you get the Spring Loaded button and catch for the glove box. Or is that stock stuff?
