WHOA!!!!!!!!!!!!!!!

$665.43?!?!?!?! For a small chunk of metal? That'* not even worth it! Please tell me I can use something like my feeler gauges to adjust it.

You may not even need that. IIRC the older models were slotted, so adjustment was necessary. But on the newer sensors, there were no slots...so only one way to bolt it on, and one position only.

Feeler gages would be useless as the gap is way too wide. I would instead take a compass/caliper and measure out the distance between the center of the HB and the tooth ring. Then, use that same distance from the center of the crankshaft to the center of the sensor (between the two pickup teeth).

I think 92 was the last year for the adjustable sensor. When changing the sensor on our 89 we used a .020 feeler gauge between the balancer & sensor.

The gap is that narrow? I thought it was much greater than that

Yeah, that'* all it is. My son held the feeler gauge from above & I slid the sensor over with one hand and tightened the pinch bolt with the other. The .020 gauge felt a little tight so we tried a .015 and that was loose. Fired right up.

92s don't. I used a piece of cardboard to set the gap.

maybe that being the transition year, you may have an early 92, and maybe mine are late 92s, idk? but both my 92s have a fixed cps.

Mine is a late 92 (6-92), and it'* definitely a adjustable crank sensor.
