Sounds like you are asking if a 67 steering wheel will fit on a 69 car.
Hold on, hold on......
I get that you are asking if the horn ring and center button will fit the later steering wheel, (presumably you have a great 69 steering wheel but don't like the 69 padding or have a 67 car and the 67 wheel is toast) if you look at the back of the 69 you will see that the spokes are super wide near the center.
So IMHO even if the horn ring would fit it would look ackward.
I know it doesn't answer you question, but to my first statement, perhaps you would be better off getting a wheel and horn ring combo that you like assuming it can be bolted up to the year car you are working on
