Mine = 2006 6.0: Also a direct fit replacement with a stock Ford OEM box about 7 years ago (original box had to contend with the Sportsmobile lift and 35" tires for 10 years - so that was good enough for me).
Obviously NOT EVERYONE has had issues with Red Head, but at that time
my Shop encouraged me not to use them since they had already encountered numerous issues with Red Head's failing. Admittedly, I have no idea what consumer feedback is out there currently concerning them...hopefully positive.
