7mm swivel head socket (1/4" drive) and a telescopic magnet make this evolution MUCH easier.

^^^^^^^^^^^^^^What Bob said ^^^^^^^^^^^^^

Crazy and I did it in an hour last time ... That's cause "I" was
slowing him down on the beer drinking side.....

A 3/8" "wobble" or two is very nice. Also, use electrical tape
on the spark plug swivel socket (HEH so you can get it back out)

The locking 1/4" extensions are VERY nice, but electrical tape
works almost as well.

Tape the 7 mm to the swivel with thin overlap on screwhead
of the coil screws.... This let's you get tehm back in without
fisshing for 'em when you drop them (ASK ME HOW I KNOW!!!)

Ummmmmm .. .that's all I remember ... ALCOHOL induced
memory loss

PS... Best advice is find a lightning brother that has done
it already ... and watch and learn ...

 

The first time took me about 1hr and 15mins now I can do it in about 30-45mins.. Just make sure you have the 7mm socket and a magnet or claw.
