Working on a 2016 Explorer 4wd 3.5 Limited. It has the HD 352 mm front brakes. There are 2 rotors. A regular HD one and one called a top hat. (The second has vents in the hub of the rotor.) Are the 2 interchangeable?? They both are the same size and I have not taken it apart yet. I ordered the regular one. Of course this one is the top hat one.

 

Just passing on what I found. I opened the box and questioned were answered. Also swapped them out with no problems so far.
