Will a 1991 Camaro steering column fit 1989 Camaro?

While both are third-generation Camaros (F-body), there's a chance they might *not* be directly interchangeable. There were some minor revisions throughout the third-gen production run (1982-1992). The differences might be subtle, but enough to cause incompatibility in mounting points or even the shaft diameter.

It's best not to assume compatibility. You should compare part numbers from a reputable parts supplier (like a GM parts catalog or a well-known auto parts store's online catalog) to be certain the columns are indeed interchangeable. Visual inspection might not be sufficient to identify all potential problems. Even if they look similar, slight variations could lead to problems with installation or steering functionality.
