The 'end all' e34 front strut mount reference thread.

[ivoe12]

The info in this thread definitely gave me a lot of answers and saved me time ty.I am currently in the process of changing the strut mounts(top mount /guide support) on a 89 ALPINA B10 3.5/1, by the looks of it and the diameter of the shaft and nut its V1 type (PN:31331134096) ,however i am a bit confused because the PN on my strut mount is 1134900 and there is no information for a part like this anywhere ,now i am wondering can this strut mount be Alpina specific.
Here's a picture of the Strut mount in question
