Here is the service manual for the gearbox. Look on pages 16-18 for the adjustments.

My question It feels like its harder to steer than it should be. is there a pressure adjustment to increase hyd pressure to the steering box, or maybe this one is just worn out??? it's really a pain in town when you have to wait till the last second to start your turn and really need to move the steering wheel in a hurry. It's so bad I even thought about one of those steerling balls, but I heard there illeagle in some states.
if the steering gear preload is adjusted too tight, the steering will not "return" or center properly, therefore, when driving at road speed you would be always correcting the steering to eliminate the linkage as a problem, try turning the steering right at the input shaft/u-joint... does the "lash" feel different when the engine is running? ...compare movement between input shaft and pitman arm

Thanks bob, and spiltshifter, I finally found the right manual on steering box. it's TAS 65. I going to check the spline and clamp like split said. and I never thought about haveing the engine running while checking the lash. I do think I have it adjusted to tight. Thanks for the comments, suggestions.
