Here is the part number for the Motorcraft fans. AL3Z-8C607-A When I bought them a year ago they were $160. They have since gone up. Now around $200. I ordered a dc controller from Brian at dccontroller.com. This I would learn later was a huge mistake. About 30mins ago I ordered this controller Painless Wiring Part 30140 - Dual Fan Controller by Painless I can't wait to install it! Has all the features I wanted! The Motorcraft fans are awesome and will blow you away at 100% pulling a mere 15amps each. You can feel the air flow through the grill. Makes the ac good and cold while sitting. Very worthwhile mod and you will pick up 15 or so hp at the wheels.
