Hi, again)
I found with a lot of effort in my email about a smarty trend order winch I made a long time ago.
A lot of things have changed now. Technology is changing all the time check out their website.
I hope I was able to help you, I was based purely on my experience.

Never apologise for asking a question how else do we learn
Take a look at www.realoem.com a BMW online parts list put the last 7 digits of your Vin into the search box it will bring up your model, then look in the seats section. Scroll to the part numbers and double click the part number it will show a list of alternate part numbers and models they were used in.
If available that is
