The 300 horn button and the 65 Malibu horn button attach differently. The Malibu has two metal spring clips (one on each side). If I remember correctly, the 300 is secured by a rubber ring between it and the part that actually makes the contact to blow the horn.
If my memory is correct about the rubber ring, then you can use a 67 Malibu horn button because they also use the rubber ring attachment. Don't know if the outer diameter will be exactly right though.
Good luck!
