Sierra upright dimensions
There is a Ford Sierra upright drawing circulating through the Locost forums. I am referring to this
After i made a check measurement to my actual Sierra upright, i saw that this drawing is not that accurate. For example the distance from the centre
of the hub to the steering arm centre is NOT 110mm but 120mm.

The diagram shows the dimensions to the actual balljoint, not the hole. Mabye this is why? Am i right in thinking that when in its right orientation,
the steering arm is angled?
Have you checked the other dimensions? When i come to make my upright i will be using this as a guide to dimensions to keep the right suspension set
up

Looking at the picture, and at the diagram, it is clear that there is a discrepancy.
Have you found any others yet, Echidna?

The centre of the ball of the ball joint should be always at the same point in space, never mind the angle of the trackrod end.

Not yet, because i must fit the upper and lower balljoints, i must then find exactly where the "ball centre" is and it's a pity to
ruin the self-locking nuts...

From a first check the "10" and "5" dimensions seems about right, not 100% sure about the "5" dimension though!
The dimension "110.89" and "89.62" seems to be accurate too!

Looks about right to me.
The steering joint hole is inclined and isn't how the the sketch suggests. The 110mm dimension is the blue arrow dimension.

The inclination is a slight one and by no means you could come with a 110mm dimension. Again:
