My initial thought is, substituting the soft top probably becomes logistical nightmare at this point in the game..
While It may sound like a simple process, I can virtually guarantee it is not.
Maybe 2022????
You've probably already read my conspiracy theory on the 2dr tops, but for the uninitiated, my built wild GUESS is the 2dr having no other top option takes a priority for the tops they CAN build, along with FE tops.
After that, any extra top capacity goes towards general orders.
Just a wild guess..... zero inside info.
Day 1 res first 3 hours, Feb 6th order; May 25th? scheduled for build, July 15th Build date, Dirt Mountain 2.5 months, delivered into my loving hands Oct. 8th
