I think I have identified a modern / readily available replacement for the rear ABS sensors.
2006-2011 Camry / Avalon front wheel speed sensors are basically the same design as the stock MR2 rear sensors, and with a little work fit the stock knuckle.
The diameter of the sensor is a little bit greater than the stock sensor, and the length is a little longer. However the length from the ridge by the flange on the new sensor to the tip is perfect. If you drill out the stock knuckle with an 11/16" drill bit the sensor fits and bottoms out on that ridge. The spacing to the bolt hole is slightly different, but close enough that a bolt will thread in. Shim it with a few washers or get fancy and make a spacer if you want.
The electrical connector is different, so you will need to splice on the old connector. You may be able to buy the correct pins for the old housing from someplace like Ballenger Motorsports - High Performance Electronics and crimp them on and install them into the stock connector if you really wanted to get fancy. The wires on the new sensor are a few inches longer than on the old.
Of course the various brackets and clips along the wire are different, but those can be swapped over from the old sensor.
Unfortunately I can't guarantee that it is electrically compatible with the stock ABS computer (I don't have ABS on my car to test with), but I think the odds are good. It LOOKS like the same style sensor, and the resistance of the new sensor is within the range specified in the BGB (.9 - 1.5 k ohm). For what it's worth my stock sensor measures about 1k ohm, and the new one measures about 1.5k ohm.
Best part is, you can get these all day long on Rock Auto for reasonable prices. Stock sensors are either unobtainable, or very expensive.
