Mine DID need holes drilled, I removed the originally plastic in the roof and when I saw there was sheet metal where the studs were suppose to go that’s when I decided I was not going to do it myself. BTW I’m a body construction engineer at ford. Things change, we will change things middle of the year on a model. Things change far more frequently than normal due to Covid.
You’re telling me they’re drilling holes on the assembly line now? I don’t buy it, sorry. Everyone I’ve seen on FB that’s swapped parts has exactly what I described.
