I'm glad this thread is helping some folks but one question that is related to the title.
I'm sure I 'meant' to type "How to buy E39 25" driver side & 22" passenger side wiper refills" instead of just "How to buy" because that's the first line of the first post.
Something obviously went wrong.
But, how does one change the TITLE of a post after the fact?
FROM: How to buy
TO: How to buy E39 25" driver side and 22" passenger side wiper refills?
