I have an 86 2.3 16v. Every on-lines parts store i look at has two distributor caps, and two rotors. I would plan on purchsing the bosch cap, but don't know which rotor. One is about $25, and the other is about $9. I assume i have to purchase the more expensive one? lol

Click on FastLane above. Phil has an email address and a toll free phone number. It might help if you have your VIN ready. Maybe there was a mid-year parts change or they're functionally the same - one is Bosch; the higher $$ version may be OEM.
