I've mostly only noticed the large mirrors on fleet TC's around my area (northern IL) and a couple of wagons, although I don't specifically pay attention to TC mirrors while driving, haha. Here's a used passenger side one on Ebay that I found. http://www.ebay.com/itm/FORD-TRANSIT-CONNECT-Right-Door-Mirror-Power-large-14-15-15J0861-/381554926615?fits=Model%3ATransit+Connect
Doing some internet searching, it appears as though these are the correct dual glass 'large' mirrors, but I'm not sure if the cover is included (front side of mirror when on vehicle). These ones are manual mirrors, not power. Unfortunately, it doesn't show the full part numbers on the website.
