I have a rallye steering wheel that I want to install on my car, and am wondering if I have to replace the steering wheel hub to install it ? o No: The car is a '72 Skylark 350.
What wheel is on the car now? "Regular" steering wheels don't have a hub. The sport wheel has a hub. Hub goes on the splined steering shaft, just like a regular wheel would, then the sport wheel screws to the hub.
