Does anyone know where I can get a strut tower brace for a 2010 427r Roush Mustang?
Try eBay if RockAuto doesn't work out.
eBay search using "2010 mustang strut tower brace" resulted in 56 auctions. You Mustang guys have lots of choices.
Make sure what you buy will fit a supercharged car. Not every strut tower brace will work. Sidenote: I have a 2007 427R....
