Update - mobile service replaced my cameras, but not without some drama. I asked the technician to please double check part numbers, as I would like to save them a trip, and sure enough, halfway through the work, he realizes that the RH repeater is wrong (1495867-22-C), and the LH B Pillar is wrong (1092311-S0-D). Luckily my local SC had the right parts in stock, so they Ubered the parts to my house while the other cameras were being installed. They ended up putting in RH repeater 1642011-00-A, and LH B Pillar 1092311-98-F.
And now, I re-enroll in Beta and wait.
