Can you order the 24 BB with a locking differential? According to the order guide it's not possible but someone on here managed to get their dealer to do it.
Yes, that might have been me (ordered 2024 BB 2-door, manual tranny, rear locker from a dealer here in NH - order confirm e-mail received from Ford on Oct. 26).
Best suggestion would be to use the Ford Build/Price tool - you can see at least in theory what's possible and how choosing certain trims/packages forces you to make certain choices....and can do this without creating an account/logging in/submitting to dealer(s). That said - based on other comments I've seen, I guess dealer allocation can affect what orders a given dealer will accept.....
One other slightly strange thing - it does not show an upcharge for adding the rear locker to a BB, but dealer was advised by Ford that it added $495 to the cost.
