I see in the ad it does say all 62-66 models, but I know the 63 belair and impala guts are different they don't have that round flat metal disc that is in the picture, however I ordered it yesterday so will see when I get it if I can figure out how it goes together. I had been searching for several years for the correct steering wheel and horn button for the Biscayne and finally found them. The wheel was the only part that was not original on the car (had a 63 Belair wheel). So I can't wait to see if I can install everything and get the horn button to work.
Thanks Again
