Original is the same as all 72-74, the black plastic two-spoke wheel.
I don't know whether there were any available option wheels, but a friend of mine has a 73 'cuda with that wheel. So if it was standard for a 'cuda, it was most probably the same for a Rallye Chally.
Dave's page might give more info :

So I'd say only the two-spoke was available and no optional wheels.
