Just received an extension letter today in the mail, it is dated April 28, 2023 and is from Ford of Canada. The gist of it states the 21B09 "program has been extended to July 31, 2023, regardless of distance travelled."
Back down the rabbit hole, I had long ago come to grips with not paying 700+$CAN for a 275$US part. My northern Ontario Ford dealer said the program was a surprise to them as they had not yet heard of it. The dealer will look into pricing and call me back.
This thread addition is just to let others know the program appears to be extended, if anything major develops out of my call to the dealer I will add it here.
UPDATE: dealer just called 668$+tax, free labour to install. BIG nope, basically extended the program but changed nothing else.
