Spline object on a spline path

[ATHellboy]

1) Common ATHellboy, it's easy to find. Did you look for it before asking me? I feel that you rely too much on me. The Position of a spline controller is SplineController.Position.
The From and To fields of Shape Extrusion module is BuildShapeExtrusion.From and BuildShapeExtrusion.To.
2) The solution is to unpack the generator (unlink it from the prefab)

1) Dude, I think you don't understand my need! I know how to access them but as you know the From and To values are not same as SplineController.Postion although they should be, because they are based on Spline. BTW you said they are not same (Although I don't know what the reason is) and I should sync them (if it means how to make them same) and because it is rely on your API I should ask for help from you.
Now you know what the problem is ?

2) I did understand this solution but it is not really a solution! I made that prefab for a reason l, to make change on all of them if we will need to so by unlinking I will  lose this functionality which is most important functionality of prefab.
