how to change spark plugs on a 1989 ford aerostar van?

LOL
THIS IS A FUN ONE.
let me guess your having troubles getting them out of the passanger side of the motor. This might sound funny but i find it easier.
#1 jack up the front passanger side and remove the tire.
#2 please use jack stands under the van to hold it up.
#3 Then you can reach up and remove the hard to get at spark plugs.

p.s. don't forget the jack stands as you need to get right in there.
