What are these called ?? (273 Valve cover wire holders)

Hi guys,

I need the bits on the valve cover that hold the spark plug leads in place.
It's a 65 273 Barracuda, but I can not think of the name of these damn things. I'm searching around but must be typing in the wrong thing.

Figured I'd ask.

Your photo is the '67 version. They're different than the '65-6 engines, which use individual wire holders and not the dual holders. The valve covers reflect that change. The '67 covers have a slot between the wire openings in the aluminum finned bracket which the holders lock into. The '65-6 valve covers don't have that slot.
