Where to buy a crank sensor?

We usually recommend our hot air customers to convert over to 86-87 style sensors. They are far more reliable and easier to come by.
Sounds good to me,only question now is where do I get the wire harness to splice into original harness.Looks like the 86/87 sensor is set up to accept the wire harness right at the sensor whereas the 84/85 sensor has 10 inches or more of wire.Thanks!
