Does any one know the thread of the track rod (not the track rod end) of the mk2 escort where is screws in to the rack

I suddenly thought whether the track rod from my BMW rack would fit the escort rack?

The bit i mean is the left hand bit on this pic:

i don't think it screws in anywhere? isn't it a ball joint? so its got a ball on the end of the rod, and there's a sort of cap that screws over it all to hold it together?

if you look on the picture i put up , there a casing in which the ball sits in, this casing a threaded part, it looks very similar to the BMW unit, so im hoping they have the same thread

Won't wash -------------------
As implied in my earlier post in the thread the steering racks used in all Mks of Escorts was designed around imperial sizes & threads.

I haver never seen a BMW that wasn't fully metric.
