Fox's have the same exact suspension as all Mustangs up thru 2004 (exc irs cars of course). The 2005 went to a 3 link with panhard bar.
did he lose his driveline1st? looked like he planted driveshaft and that ripped axle off. now you see why you need a driveshaft loop
With great big slicks, I'd have thought the tech inspection would have caught the missing drive shaft loop...
