There are 2 different variants and I have seen and have both alternators and bolts, the number is based on the the production date.
Both alternators do not have a nut insert the later ones do after 96', it is some what hit and miss. Some reman 80 amp alternators may or may not have this fitted.
The number you provided 07 11 9 900 630 is the correct number for the alternator lower bolt. Same diameter same length different pitch (1.25)
Thanks to dogee for posting the correction
So to the original poster dejan_da_dude the bolt 07 11 9 900 630 has stated by doogee is the one you will need.
