Looking for information on the wire loom support that clipped to the pinch weld 1967-8 A-bodies.
Did all A-bodies get one?
Are these the same as used on the '66 and earlier cars?

Also was a clip to hold the wire for the brake warning switch?

Attached is a closeup of the clip on a '67, as well as a photo of '68 GTS unrestored with arrows showing the locations I'm asking about.
