You can take your A/C hose to a shop and have a custom one made. Probably won't cost much differently than getting it from Tesla, the ends are standard fit. This is what I am doing for an 84 vanagon westfalia I'm restoring right now!
Thanks, that part is in and I'm scheduled to deliver the car to the SC tomorrow for work. (it was delayed to install 'cause I was traveling out of the country last week on vacation.)
