The bracket tweet posted looks like the same setup that Fan2488 turned me on to for late model mustangs to fit.
thats what i have on my maverick. yes the cap does screw off to get to the wheel bearings. very nice brakes that stop my car on a dime.
note that you do not get the cross-drilled and slotted rotor in that auction. That will be extra. Also, I can beat that price on the aerospace setup, on both slotted/drilled and not.
