Only advice is if you buy an Accufab, which I do recommend, they don't come with the TPS - you have to transfer from your old one. Easy enough, but Ford used thread lock on the screws which can make it a challenge. Secure the TB in a Workmate or vise (between two wood blocks) or something so you can bear down on the screws without the TB itself turning. Then get your best screwdriver and bear down and crank on it, avoiding stripping at all costs. Mine we really not too hard, but I was prepared for the fight! I guess it depends on how old the TB is and how long it has soaked up the engine heat to form a nice, firm bond. Again, regardless of this minor challenge, I highly recommend the Accufab TB (and their plenum)...Quality always costs a little more, but once it's in your hands you'll understand why. They make nice stuff.
