Are all sierra steering wheels same?

[Shorty]

Well I got a steering wheel but didn't come with the bolt for fitting.
I believe the thread is blue but I am unsure if this is just threadlock or if it is to show that the bolt is a specific fine thread.
Does anyone know if ford will still supply them or know the bolt size needed.

There were some of these (blue thread) bolts holding the rear bearing carriers, does anyone know if they will be needed as I might as well get them too as heads were pretty worn.
