That is very good, that you can understand Japanese, so keep this site under your favourites, very good info
http://dd.jpn.org/BMW_HP/index.shtml
There is a google search on that site, but of course in Japanese, so you have to find te right Kanji or Katagana to search. Use google translate. But sometimes it also works when you just use the english/german BMW abbreviations such as CCM, then for example this come up

So back to the brackets, now you have to learn also German
My friend Wolfgang in Germany has a good E32 site
http://www.e32-schrauber.de/bmw/
Index is in German, but a lot of links are in English then.
On my websites there are links to dictionaries related to car specific parts names.
In this case go to Innnenraum = interior
click Heizung Klima = heater and aircon
click Klimaanlage = aircon
then you find Ausbauhilfe Klimaautomatik =help to repair climate automatic
and then you find this, here the direct link

On the German board the member ks-na has made some brackets to avoid this breaking of the stepper motors, actually he wanted to make them available for others too, but long time no answer from him, I ordered some. Maybe you can make them and sell them. Bimmerboar E32 forum members would lik to have them too.

See post number 10, where you have to open a pdf file. You can only open that file after you registered on the German forum, but that you did probably already, becaue you want to see your car there in this thread

will be added soon
The final brackets to stop the breakage of the stepper motor in the future are in this posting
