If you are concerned about whether or not your order was actually accepted by Ford. Give Ford Performance a call at 800-367-3788.
They will ask for your dealer number and order code to look you up in their system.
I called today and they at least confirmed the dealer did place the order for my Gen3 with 37s.
The rep told me to let you guys know about this resource.
Hope this helps give someone some peace of mind.
Thanks for this! Just confirmed mine: build date 7/19. Fingers crossed things go as planned but I'm not holding my breath...
