The facelift model S gets new part numbers 1058007-00-Rev, and 1057851-00-Rev. I replied to the tesla service chat with a screenshot showing a "G" revision. They responded with "thank you for the update." I will update with what they actually allow me to buy.Sorry, no idea. Did not know the "F" are crap.
I just know what Tesla told me and that is that i need whole new "package" due to new version of the "housing" - no idea thou what this means.
Maybe the "G" are for newer tesla's ?
