I may not be correct, but my memory tells me that Chrysler offered 2 different Tuff wheels in the early- mid 70s... one was 15" and the other was 14". I had actually bought a new one (14 or 15) but was displeased with the very slippery feeling, as well as it was still too large in diameter (progressively smaller steering wheel gives another advantage for quicker steering response... for autocross, etc). Further, the factory Tuff whel was a little too thin. In my opinion, the thicker wrapped leather grip would be much better and desirable, as well as IF they could make it in the 14" diameter, or even a 13-12.5-12 offering.... 15" is absolutely too large... imo, for my needs/wants. I think Grant's Tuff wheel is 15" or slightly larger.
