Steering wheel center pad...horn buttons...airbag.Hi I know it's a common thing on these 93 era Park Ave's and Lesabres with the horn buttons falling off. I just saw one in perfect shape at the junkyard which I'd like to get for my 93 Park ave.Any issues with removing them and replacing them ? I know the airbag's in there. On the back of the steering wheel I see the holes where I assume the screws are that hold it. Without checking with a mirror to see what they are.... are they Philips ? Torx ? Thanks for any help / advice. Tom
