I didn’t have access to the original sunshades and had to look for other options online. Thankfully, 3rd parties had me covered.
I got custom-made sunshades online, and luckily, they fit the windows perfectly. I think even better than the regular ones. These sunshades from https://snapshades.com/ use magnetic strips to hold onto the window’s frame and therefore cover 100% of the window’s surface and don’t let any dangerous UV lights inside the car. It’s really important for protecting the kids from the Sun that can be pretty dangerous in my area.
The Ford branded Covercraft is excellent. I have one for my RS and it is superior to all other shades I have ever used. Lived in Florida for 30 years so I have decent experience with those things. It's a little bulky because its a stiff material but it just works better.
Have the Ford one and very happy with it. It is durable and fits well, though it is stiff and a little hard to fit if you’re in the car. The “best” part of mine is that it was free as as “atonement” for a dealer foul-up!
