I cannot remember if my own 3-spoke metal steering wheel came from a 1990-1991 B-Series or an RX-7. If it looks the same, it will fit (2 decades ago I pulled a few, and have sold them all). The center plastic horn button is apparently still available new (gray, Mazda FA 54-32-800A).

1992-1993 B-Series elephant-foot steering wheels will also fit (sold the one in the picture long ago).
