Help: Remove/Replace 1967 Barracuda Steering Wheel

The only special tool needed is a steering wheel puller. Yes, you need it. No, you can't remove the wheel without it.

Remove center ornament. Remove horn button (3 screws) and lift it off. Remove horn switch wire from its terminal and lift the horn switch off. Now you can see the steering wheel nut. Hold the wheel in one hand while you loosen and remove the nut (and washer) with an appropriate wrench with the other. Install the steering wheel puller's two side bolts into the drilled and tapped holes in the wheel hub. Turn the wheel puller's central stem down until it contacts the steering shaft, then keep turning till the wheel pops off the spline. Remove the wheel-and-puller assembly and remove the puller from the wheel.
It depends on how tight the nut is. I've pulled many without a puller but they're cheap so it makes sense to have one. The stock wheels have a master key so they only can be installed one way. If the wheel isn't centered, it's because that last one who aligned the front end didn't do their job right.
