RPM Sensor location and size

[DGraber460 at aol.com]

The sensor is located on the front edge of the bell housing, at the rear of 
the engine, above the Speedo cable connection, on the driver side. There are 
2 identical sensors. One is the TDC indicator (references a steel rod on the 
flywheel), and the other is the RPM sensor (referencing the teeth on the 
flywheel). On some 5k engines, they are Siamesed on one mounting block. The 
RPM sensor is the front most of the 2. On other motors they are on separate 
aluminum mounting blocks held in with 1 or 2 10 mm hex bolts.
They are accessible from above, but the water cooled turbo cars have a few 
more gadgets in the way. It should be a simple "plug and play" operation, 
maybe 20 minutes.
