Folks - again many thanks for the replies - As I stated I would feedback after getting the chance to make adjustments.
After disconnecting the track rod ends I was able to find the central position of the steering box and low and behold the connection between the steering connector arm to the track rod had to be adjusted about 1 inch toward the driver side. After a final adjustment of the steering box I now have very little play at all and equal steering in each direction. What I don't understand is how this could have ever been so far out. The car hasn't been driven in years, however it seems that someone has botched it up at some stage in the past.
Hopefully will get a test drive over the weekend and I know its going to be a much better steering experience.
Many thanks again for all the instructions - I thought I was going to be in for a big bill on refurbing the box
