Snapped Clutch Adjusting Rod

Hi All,
The clutch adjusting rod has snapped on my 1968 Minor 1000.
I notice that the rod itself is not lying horizontal, there is a tilt at the threaded end.
Images attached.
Should there be a tilt? If not does it mean that the part the threaded end goes through is too short or maybe fitted incorrectly?
Other than replacing the rod which other parts should be replaced? Please send a link if you can.
Thank you for reading and your help/advice.
Regards,
Robert

Is the tilt simply caused by it being snapped in two? Was there a tilt before it snapped?

Thanks for your reply.
I wish I knew but the components were fitted before my ownership.
I'm trying to find a stock photo.

I think it is simply hanging down where it snapped. It should be straight, looky here:

I would simply replace it.

Agree but I am assessing whether the threaded end of the rod should be exposed/visible before the rod enters the clutch fork.
This is not the case in a stock photo.

I wouldn't worry about that, it will depend on how much adjustment has been made. When you get the new one, if the free movement at the pedal is too much, then move the adjusting nut towards the rear of the car and vice-versa.

The snapping of the release rod is not an uncommon occurrence.
There is enough flexibility built into the operating linkage to accommodate some degree of mis-alignment.
The release arm moves in a arc and for the link to operate correctly a special nut with a convex/spherical face is used and which fits into the concave hollow at the end of the release arm.
The stock photo above appears to have a bicycle hub nut fitted to the operating rod between the release arm and the special nut so is not a good example of how things should be and should be ignored.
Whilst the gearbox in the photo above is of a 'A' Series gearbox it is not a Morris Minor gearbox as it has the threaded holes for a hydraulic slave cylinder. The bicycle hub nut may have been fitted to make a hybrid clutch work.
Just examine the rest of the clutch release linkage and if any sign of wear to the various parts replace them.
Make sure that all moving parts are well greased/lubricated.

Well spotted about the 'bicycle hub nut', Phil. What a bodge! That in itself would prevent the thread showing the other side of the release arm.....

Come to adjust mine today and found the reason for excessive free play that was getting worse. The adjusting nut and locknut could be turned with your fingers
Self adjusting clutch
Once the play was adjusted the locknut was pinched up against the adjusting nut with two spanners as intended. Hopefully problem solved.

Couldn't make out if there should a bush in the clutch operating fork where the rod feeds through, any idea?
Thanks

Don't think so the arm is cupped and the adjusting nut is domed which gives it angular movement during travel. Put grease at contact area.
Good luck with the repair.
