Try HERE and do a part search (with the part numbers you have) to see if they are cheaper than the Stealerhip where you are. I know for a fact that they were 1/2 of what the Ford place in Knoxville was when I ordered parts.
cheapest found so far is Tasca Auto Group | Your Online Parts Dealer
I ordered some stuff a while back but misplaced Andy Serpa's card during my move at work. Everyone else had the part listed for $98 and this place has it for $88. Every dollar counts.
