Help with horn button size

[racingdewman]

I recently installed a steering column that I pulled from a truck a few years ago. I installed it in my 64 c10 and recently decided to add the horn button and it did not fit. The standard button appears to small. I have two other steering wheels and the standard button fits on both of them. The wheel on my truck has a nice feel and it feels smaller than the other two I have. the other two are thicker and heavier. Could this wheel be a deluxe wheel and need the deluxe button? Are the deluxe wheels thinner? its the same diameter but feels thinner.

mine is the opposite with about a 1/4" gap around the horn button. I gave up on this thing though. my column is too jacked up. I have installed and re-installed this horn kit at least a dozen times but i can't get it to work. This last time got it to work but goes on when i turn the wheel.

I am going to go back to an alternate push button setup. You can see the current yellow one on column my uncle did years ago lol. Just need to find a smaller one that looks better and mount elsewhere. Maybe the old unused throttle knob.
