When I ordered my new truck last year, my WS updated 4-5 times and the number your referencing was supposed to be the date of the WS. Interesting that some are going back to their old date. Not sure what to think of that.
I think if yours ships convoy you can expect it much faster. I ordered a new F150 last year and it was at my dealer two days after being built. Granted that was from going from Michigan to Ohio via convoy.
I'm thinking the assembly line photos only go to reservation holders? This was a walk in order I placed since my reservation is sitting at Chapman and who know when that will get scheduled.
Mine isn't showing up in the pizza tracker but if you use the below it's there.

Installed these on my wife's OB SAS today and I was pretty happy with them considering the price point. I will say the fronts took some getting used to, but they do look better in person and I'm pretty satisfied.
Had 3/26 build day yesterday.....today chat tells me it's "In Production" with no build day listed. On the new tracker I have moved to "In Production" but no WS yet. The Pizza Tracker isn't working at all for me right now. I feel it's getting close now!
