Roush axle backs fitment questions
I just purchased a roush axle back kit from a guy I know, it's for a gt tho. I got a good deal on it cuz it's only got 500 miles on it and still looks brand new. That guy sold his car and took these off. How hard would it be to put it on my 14 3.7? I've heard these on YouTube and they sound good. I'd love to use these cuz I got them so cheap. Thanks in advance!
