It should fit the following:
83 Turbo
84-89 4cyl w/eecIV
84-86 6cyl w/eecIV
84-85 8cyl w/automatic
86 8cyl 5.0
90-93 5.0
From what was discussed at FEP it should also work for 87-89 too.
Ford wants $70 for just one!
I'll sell them for $29 plus shipping for one and $28 each plus shipping for two.
Shipping for one is $3. Shipping for two is $4.25.
