1960 Grille Question (Headlight Assem)

[DaddyOh]

On a 1960 grille, there is a vertical adjustment screw and a horizontal adjustment screw for each headlight. Also, in the lower 'inboard' corner of each light, there is a hooked spring. What does that spring attach to? I thought it was for the small hole on the outer ring (that holds the headlight) but seems you would need to be a circus performer to make that work...

Looked in the factory assembly manual but unable to see any picture how the assembly is constructed... would anyone have a picture that shows how it is assembled?

Thanks
