Restoration: e34 M5 (metallic dolphin)

[Adi]

If you read through this build you will see at some point I bought a donor car, white OBB77151. That car is long gone, parts taken over and quite a few sold. However, I still have then Vin Plate of that car.

Question, that Vin Plate saying OBB77151 where do I put it in my car? Suggest a nice place please.
