Part question - steering rack bolts

[tchalikias]

Does anyone have the part number for the nuts and 'locking mechanisms' (the metal caps that prevent the nut from loosening) for the two bolts that secure the steering rack to the subframe?

I can't find this part on the Dialogys diagrams, I can however find the relevant bolts (part number 7703602195).

Thanks in advance!

@tchalikias did you find the part number for the "locking mechanisms"?
