I'm in the same boat, no updates as to when stock will arrive, seems to be a common issue due to a poor design, second time I have had this happen in 3 three years. I currently have a temp fix until the part comes in, but did find another forum where it was mentioned that this part does the job and is more secure - going to see what my local garage says about it it first.
