You can 100% order a MIC top, your dealer is clueless. Now, will it take longer most likely given when you made a reservation, order date, and your build. But there are NO hardtop conversion kits until Sept 1st and after builds. Now, if you go soft-top and want a hardtop, best of luck getting one before 2023 probably at the earliest if not even later given the amount needed by Ford to fulfill current orders and orders still coming in for MIC's and then MOD's in 2023. Plus, you will be covering all the freight charges to get the hardtop as well.
Just food for thought there
