Hi brock,
In adjusting the steering on a 1927 you have the option of turning the screw part in such a manner as to use new teeth. This will tighten the steering when the wheels are straight ahead.
The two adjustments you have available are the end screw at the bottom of the steering column and the side plate by adding or removing gasket material. Incidentally, the 1927 was the last year of washers for bearings. In 1928 these washers were replaced with two ball bearing units.
Assuming you have done all the correct adjusting and still have "play", take a look at kingpins, axle bearing adjustment and 'slack' in the tierods.
Not aware of any user adjustment on the disc wheels. I would think a wheel shop could 'true' them up for you.
