Hub Steering Wheel Adaptor ...

Hi Guys,

I just bought a brand new Sparco Steering wheel (the same in the picture) and I want to replace it on my 1974 Plymouth Duster....the issue is: There are a lot of hub steering wheels adapters on ebay and I don`t know and don`t find the correct one to fit on my car for me to put the new steering wheel ...
Someone could please help me? with more information ?
