I had the same problem once. Someone left a lit cigarette on the bracket and it melted a little and distorted a bit on the top side so I wanted to replace it.
I ordered a bracket thru the dealership I worked at and the one that was shipped would not fit. They tried again, and got the correct one. I don't remember if there is a difference between the SVT or not, or if they found me one for a Mystique the first time, but they were able to eventually find the correct one.
I suspect that someone is having trouble reading Ford's less than wonderful parts catalog.
