The SCP unit is not a Ford unit, I think it's Yukon. It will work, but will need all the clearances checked once installed. Which most people do anyway.
The Ford unit is a direct drop-in, but it is a crap shoot whether you're getting the newer IRS compatible one or the solid axle one, since the part # is the same. It took me two tries to get an IRS one.
