Thanks for posting these! Mine was just delivered this evening and these seem to show that the new part number is 06400-MGE-306 which matches my receipt. Wanted to make sure because the guys at the dealership didn't seem to have any difficulty getting the part and didn't seem to know about the "hold-over" part.
I asked if Honda was paying for the delivery fee and they pretty much laughed. It was only $40 but, hey, it wasn't my idea to bring it in.
