Just discovered this thread and am following. Was considering taking an ABS tone wheel and sensor off a worn out Aztek wheel bearing and seeing if it could be made to fit the hub of my bus. Then I'd have a tone wheel and sensor I could read, and I must admit I was inspired in this by the lowly VW Beetle, which has a cable that's turned by a front wheel as it spins. Anyway after I had that, I could rig up a stepper motor to turn the bus original speedo needle, after sussing out how many counts per revolution and how many revolutions per mile. That way the front wheel (speedometer sensor) always turns the same, versus the transmission output shaft which can turn at 5.57:1 or 7.8:1 depending on high or low rear axle range. There was a little switching gear reduction adapter from the factory, but it was disconnected when I got the bus in 1993 so I never had much hope of it working. If I really wanted to, I could even make a little motor that physically turns the original speedometer which does still work. Then I'd even have odometer. There's lots of room behind the dash, I think I like this idea.
Failing the sensor tone wheel, I could also just cut out the correct hole diameter into the center of a steel bicycle chainwheel, which would give me whatever number of teeth I needed. I could do it to each side then put ABS on my bus :-D
