steering wheel adjustment

[joebuick]

Hey Guys,,, I need some input on how to adjust or "center " the steering wheel on my Grandson's 80 K10. It is off by about 3" from being centered. We did several changes from the time we started this restore from installing a 86 tilt column, replaceing the steering gearbox. The steering wheel can only go on in one position due to splines, the slip connector at bottom of column is also splined with a bolt thru it, and the rag joint connection to gearbox also has a bolt thru it, so the only thing left is the "adjustment" on the tie rod arm from the gearbox to the steering arm on left front wheel. Not wanting to mess with that until I get a response or suggestion. Any suggestions? Thanks Joe r
