In early 2023, some videos surfaced from a few Model Y owners who were able to get Tesla service to install the parcel shelf in their older Model Y's. Some of the repair techs were figuring it out on the fly with no official training on it. When others, including myself, contacted Tesla service, we were told Tesla isn't officially offering a retrofit yet even though the three part numbers were provided. My request was declined. Anyone else have luck with getting this retrofit?
