I was in a similar pickle a while ago, and had one made from magsensors.com They don't list a 2-pulse/rev Hall Effect sensor, but they can make them in a couple of weeks. Their website isn't the easiest to use, but search under 7/8-18 in the thread size box, and look at the pdf's of the sensor dwgs, and you'll see what you need. You'll likely have to give them a call and ask for the Hall Effect engineer/guru, tell him what you need and they'll get you squared away. I needed one as a pass-thru to go on the tranny housing to send a signal to my ECM and allow a speedo cable hook-up on the outside. Just for reference, I used part number 413021-70. They are a little pricey (~$120) but they are nice parts and well made. HTH, and good luck.
