Changing to a Tuff Wheel, What parts do I need ?

1970-1976 Dodge Charger Parts | MW799 | 1970-76 Mopar A & B-Body Tuff Wheel/ Rim Blow Hub Adapter | Classic Industries
Use your factory horn contact switch that’s on your existing wheel on the Grant wheel and pull the metal adapter piece off the horn pad of the grant wheel. It has the same expansion spring clip as your existing horn pad will fit onto the factory horn switch.

Thanks I ordered the adapter from your link, they had a online promotion code so it worked out good. I also ordered the Grant Wheel from Amazon. If I heard you right that's all I need to complete the job.
