Did you actually check pricing at the dealer yet? I don't know about that part, but every once in awhile they have some crazy low pricing on stuff.
I now buy a lot of the little things for my Buick from the GM dealer. Trim, pieces, keys and cutting, clips and brackets, all come in at less than the auto parts stores and, in some cases, even less than the junkyards.
Very surprised the first time that happened, but it's been pretty consistent now for several years.
Hopefully Ford is following suit. But as always.... Your results may vary!
Good luck.
