I am running this part number on my 2000 and can confirm it is an exact match (and if you look on the Meyle website you can see they list the 986 as a match - unsure why other sites haven't picked that up. I think that is why you can't find the 986 TRW front arms any more, because TRW also makes the 997 arm which fits)
In my opinion the TRW ones are the way to go for the rears. Check this thread for an install guide and also some alternate part numbers if you want to go with the updated 987 part:
