Ok I have the part #'s for my VSS, but my problem I am running into now is that each part # (3 of them) is made for a certain RPO code. Well my prob is that my RPO sheet isn't in my car, so ***hole took it out, what I wanna know is do any of you know what RPO code i have with an 89 Formula 305 TPI, 5-speed, and 3.42 gears? The 3 different possibilities I have are D9A, D9B, and I believe D9E. I hop someone can help me as this is driving me insane, I hate the 7-8 mpg and the service eng light

Ok, someone verify the part #. I found something out and now I think the part # I need for the VSS is a #10456087. Is this correct?
