Are the steering wheels all interchangeable between the 1982-1992 trans ams/firebirds? Do they use the same spline on the steering column with the single hub nut? Are the horns all hooked up the same way through the little spring/wire connector?

 

aside from the air bag wheels, i believe so

 

82-88? steering wheels will interchange, (my 85 has an 82 wheel) i'm not sure about the airbag ones,
