Hello
I need your help to try to repair the Throttle Housing of my bmw e21 323 iA, I saw a piece of white plastic
had disappeared and that the other is crack is likely to leave too,
I can not find the piece on realoem, and no store offers it for sale, has the case broken and good but the plastic parts are broken as well
can you give me a replacement or repair solution thanks for your help.

Apparently these are NLA indeed. Perhaps a circlip on either side in the narrow section will help? Your hardware store should be able to help you out there.
