What's needed for stock steering wheel change?

The Rimblow and Tuff wheels use the A/B adapter which is not used on the S79 wheel. S79 goes right onto the column. You will need 1970-up S79 wheel as 69 is different. I say up because it was also used on 71-4 cop cars.

Thank you, if I'm understanding you correctly, you're saying the Dart already has the hardware needed for mounting the S-79 wheel? Is there any other hardware I would need to get? Also, are the connections for the horn the same?

Here is the best image I have on hand of the steering column. Is that "A/B" adapter internal where I cant see it?
