Sport steering wheel assembly

I am installing a sport steering wheel on my 72 skylark. I need a diagram or instructions on how the horn assembly is installed on the hub. Under or on top of the wheel???
Thanks
Tim

 

Goes on top of the steering wheel, held in place by 3 screws.

 

Ok, that's what I thought.
I do not have the horn button, where can I get one?

Thanks
Tim

 

Nobody makes BUICK horn button centers. I believe someone makes them for Olds and Corvette/Chevelle. You will then have to find the BUICK center.
I have seen them on Ebay.

www.nationalpartsdepot.com carries the horn contact and other sport steering wheel parts for Chevelles which uses the same wheel as Buicks.

www.zip-corvette.com carries Vette parts and may have more selection.

 

NAP has the horn spring assembly for $2.99 but they want a minimum $7.00 shipping!

Good luck on the horn button, Tim. I used to have an extra I'd send you, but I dropped and broke it five or six years ago. I could have cried
