117 and 107 isn't bad, ford parts online puts them at $130 and $150
BAT has them for $175 each
I got my set from 95blackse for $105 each plus shipping
they are a pain to change because on the drivers side three bolts are under the trans/ drive shaft and the passanger side has one under the drive shaft
you will need to drop the subframe or move the engine to get them out
moving the engine worked on my zetec but i don't know how much clearence there is on the duratec to do that
