Was wondering about the diameter of the sport steering wheel for olds in 1972 my original stock wheel measures about 15.5 I've seen some sport wheels advertised as 14.5 claiming to be original I'm looking at one with no hub or horn button for 100 any help or thoughts would be appreciated

 

The large ones, which only come in black, were used on the 1970-1977 Cutlass/442 cars. The small ones, which come in colors, were used on the 1975-1980 Starfire. The hub, horn button, and contact are the same for all of them.

 

Thanks joe the one I looked at was the smaller version I'll keep an eye out for the correct one
