Steve,
I'm not a mechanic but I looked under the hood and saw that the metal rod that opens your secondaries is not attatched to anything and found and bought the 7 dollar bushing. Your certified Ford mechanic should be better than that and if it did take them that long in labor shame on them! They need training and not at your expense.

'98 SVT #1838 of 6535, every mile's mine! That makes no one to blame but me.
