I have no answer for you. I don't work at MAP. I've never seen the external "sealer" until your picture. It's not on any vehicle I currently own. 2018 Escape, 2018 Focus, 2018 F150, 2011 Escape, 2010 Taurus or 2008 Focus.
If anybody can explain why it's there, I'd be interested. It is...
I've worked in an assembly plant for the F-150 for over 10 years, and both the steel and aluminum doors have never had any "seam sealer" applied to the outside of the seam. There is, however, a sealer adhesive applied to the door outer skin before being mated to the inner and that "seals" the door.
I bet that number is the week of the year that part was cast. That would put them being produced the last week of April, first week of May. OP's truck was built in June.
The way to tell would be the clockspring part number. Check both of them and see if they match. If they do, you could make it work. If they don't, for safety reasons, I wouldn't attempt it.
Ford did give Crew builds precedence over the Supercab models. Could be a money thing or simplifying the build process while launching a brand new vehicle from the ground up. Or a little of both. Ford did the same thing when the aluminum F150 was launched.

Long thread. Tutorial in post #1 along with a detailed feature list.
I got my heated steering wheel done on my 150. I'm thinking this can't be retrofitted into the Ranger unless there is an exact match...
