Turning Circle question

[doctor4766]

I'm curious to find out if there should be any difference in the turning circle from left to right on my '69 Charger.
It seems that the turning circle is smaller on full lock left than right.
This makes negotiating culdesacs on roads designed for RHD a little difficult at times and often a 3 point turn is required.
Is there something wrong with the way my front end was set up or is that just how these cars are?
Car drives perfectly in all other ways.

The steering wheel, steering box, pitman arm and tie rods all should "conspire" to allow an equal amount of turns left and right. A power steering car should have approximately 3 1/2 turns full left to full right. Manual is about 5 1/2 turns total.
There are steering stops in the box along with stops built into the lower ball joints and lower control arms.
Mess with any of these and it could affect the amount of turns.
The steering column coupler and steering box input shaft mate together with what is called a "Master Spline", it is a small section where one of the splines is left out, essentially a flat spot. The coupler and shaft have these and they need to be aligned and mated as such. If the coupler is attached without these points being aligned, the tie rod sleeves would have to be rotated to get the steering wheel to be centered.
Sometimes, people pull the steering wheel and reinstall it to get it centered.
In short, if the car has been worked on by anyone other than an assembly line employee in 1968-69, it may have been been changed and possibly be causing your problem.

Kern dog is half right

If the steering column or steering wheel are not installed on the master spline like factory to make the steering wheel be looking straight ahead when you are driving straight and have been put together wrong and you ARE driving straight when the steering wheel is centered I think your lower adjustable tie rod arms may be out of adjustment

Mine were

I have had everything apart on my car and back together so I know all the splines were lined up but when driving my steering wheel was off by about 1/3 of a turn to make the car go straight
I started changing the tie rods making one side longer and the other side shorter to get the steering wheel looking straight again
My car was making two different size turns before I did this

Look under your car and see if you can tell there is a lot more thread showing on one side of the car vs the other
Worth a shot

"Turning circle" refers to the diameter of the circle (curb-to-curb) made by the car, not the steering wheel. In theory, it should be the same left/right if the stops are contacted in both directions.

Kern dog is half right

Thanks for giving partial credit but then please explain how I am also "Half Wrong" .
You wrote essentially the same thing that I did.

Ok, interesting stuff.
Once we had finished replacing ball joints, tie rods  etc I had the car shipped to a specialist (WA Suspensions) on the other side of town to set it all up and do a wheel alignment. The guy there had a reputation for being "the guy" to see for Chryslers.
Just checked and the full lock left only takes 1.5 turns whilst to the right takes 2.5
Don't know if my small sports steering wheel has any affect on that? 
Anyway, the car still drives perfectly even after 10 years and just over 15,000 miles so I've otherwise never had a reason to doubt the job was done correctly other than this. Oh and the tie rod arms appear to be about equal on both sides.
I'll probably just leave it alone until I need another wheel alignment at this stage as there is absolutely no odd wear on the tyres.

The particular steering wheel shouldn't have any effect.  I'm kinda surprised it drove as well as you say it did with the steering box not centered.  Supposedly the steering box has a "high spot" when it's centered the result being the car should feel more stable
