offset handle ratchet helps, but from under the car is what I do

Re: 5.7 L98 REAR SPARK PLUGS. HOW DO I REACH THEM??
They can be done from the top with a swivel ratchet, a solid ratchet and the right combination of sockets and extensions. IIRC, I use a straight, non universal, socket with a 1" extension and swivel ratchet on the passenger side to clear the AC housing. On the driver's side, I use a universal socket and whichever extension works. To avoid broken knuckles, dont use universal sockets with a swivel ratchet. I use Snap On tools which allow the best clearance.

Also, please turn off the Caps Lock key. It's poor netiquette, it's like you are yelling all the time.
