When I put one one my '01, I got a pre-drilled unit from Amazon, it was a Reese brand. the bolt holes lined up perfectly on the chassis rails. Word of advice, drop the spare tire, the clearance needed to put the hitch in is more than what Ford left up there, once the hitch is in the tire will fit like a glove. Also, depending on what tires you use, you might need to deflate them some to get it to winch all the way up.
