Simon,
On my early 73 2L they were all done in the same
Satin Black for both the F & R sway bars at all parts, as was used on engine tins, gas tank, etc.
There might be pix of them in the O&H Forum's "The few, the rare..." nailed forum of Steve G's/smg914's Sahara Beige all original example there. That topic is a great resource for checking stuff like this.
IIRC the Body section of the 8-9 volume factory shop manual has a paint reference for that satin black (you can buy the manuals on CD from AA & maybe other vendors or a member for about $30-40) - or you can have a pro auto paint supplier use their "gun" to match from one of the metal bits where you still have the original satin black on there.
Oddly enough - there are different blacks & whites, just as with the other colors.
Good Luck!
Tom
