I tried putting it on the steering box shaft first, too annoying.
Put it on the s wheel shaft first is easier but you are probably correct, if you lined the shaft on the box with the coupling first your steering wheel would have a better chance of being straight since the top side only goes on correct or 180 out.
I will be under the steering wheel working on turn signals so I will try to straighten the wheel then.
