Get yourself down to a good tool supply store. Not the less than a dollar
wrench store. look through the 5/8" box end wrench (6 point preferred for
rusty plugs) for one with a deep offset. I think mine is a Snap-On brand
wrench. This means you can get to the sparkplug. I have removed the
manifold (not hard to do, just pull it away from the motor, and leave the
elbow intact. Do not use Motocraft plugs!!!! They are not plated and will
rust to the head. Then when they break, you have to buy a BIG easy-out to
back out the remains, and possibly remove the head to remove the extra
parts. I use NGK. My 351W does not have the tube.
