Steering wheel from a 69 Charger compatible with a 70 Roadrunner?

[70 RR]

I got a good deal on a wood grain steering wheel from a 69 Charger and I am wondering if it is compatible with my 70 Roadrunner. My car is in storage and I can only compare the 69 wheel with pictures at the moment and from what I can tell it looks the same. Will the horn switch and other horn parts fit the 69 wheel? My wheel was restored at some point and it isn't holding up very well but the 69 wheel is in really nice shape. The first two shots are the Roadrunner wheel and the rest are of the 69 Charger wheel. Thanks for your input.
