Tuff Wheel

I have a 70 Swinger, 340 4 sp manual steering - I'm trying to find info on steering wheel options that would have come on this car from the factory.

I really like the Tuff wheel in woodgrain and would like to add one to this car - however, before I do I would like to at least understand what "Would Have Been" correct.

I've read some of the forums here and the best I can tell, no Tuff wheels were offered for this car and the factory rimbow wheel was a 2 spoke with a pad.

Can someone tell me:
- What options were available for this car?
- Were there different diameters for PS or Non-PS? What were they?

Skylane, my other car

Thanks - Greg
