Call a couple of Ford dealers and ask if that's something they can do. I had a conversation with a member a couple years ago that said their dealer was able to do it for less than $100 and the dealer's only caveat was they kept the old cluster.
Now, I dont recall if his new cluster had more or less miles. Not sure if its something they can only add miles to vs take miles off or vice-versa.
Found a couple on ebay with closer mileage for you:
(you'd need to contact them to verify it has tach)
The two most common parts numbers are:
one should be with tach and other without iirc but ebay sellers arent consistently labeling them the same. I bought a tach cluster with a couple of thousand more miles than my car had and swapped them over when the mileage matched. I did test it as soon as I received to ensure needles and lights worked properly. Very easy to do yourself.
