[60sstuff]

Hard Tops got the long chrome stamped steel as mentioned above and the Convertibles got the little stubby chrome hook (big enough for one hanger).

The small style hook was used for the convertibles from 64 to 67.

First two pics below show 66 Convertibles with a LH hook.

Third pic shows a 67 Convertible with this hook (very difficult to see, but it's there when zoomed in).

Last pic shows a 66 Hardtop with the long stamped hook.

PS - location seems to vary a bit in the pics of the convertible frames.
