Reached out to the Ford Performance chat support earlier today, this is what they said for my build:
Looks like I have been scheduled to a day. Hopefully this stay true.
Congrats! I got my build email today as well. Base, aux switches, keyless entry, floor mats and velocity blue. I decide not to go the sasquatch route and just build it over time.
I put in a reservation this month and the next day when talking with my dealer they had me come in to put in my order. I didn't have to do anything on the ford website for it.
