<VV> Steering box question - adjustments ?

[Charles Lee]

Can the steering box in my 67 Monza be adjusted ?

It is a little loose in the wheel - more play than I'd like, but drivable, 
maybe 10 or more degrees before any noticeable movement of front wheels ?

No other symptoms, but this seems to be too much, certainly more than I'd 
really like.

If it needs replacing, is a quick-steer a viable option without being 
excessively expensive to switch ?

Thanks
Charlie
