I have 000 987 5070 as well. It superceded from 000 987 9135.
If I remember correctly, Albert fron Spain found the part # originally. Hope he still looks in sometimes!!
Tosh, I probably have enough for one car, and since you're nearest (and I owe you), I'll save on postage and send you some.
PM me your postal adddr. I'll have to look for it after coming back from Essen.
