Interesting, that's good to know. what about the holes on the underside where the spoilers can be bolted on?
As far as the spoiler mounting holes, they seem to be in the same places, but if you section the mustang valance to fit the mav. then they will be too narrow. I guess you could "square-up" the mustang valance it could be made to work. I may eventualy play with the mustang valance at some point, just to see what can be done. If/when I do I'll post a "how-to" on it.
