That's great!  Thanks.  Can you post a photo or show us something so we can see where this is

Just above the nozzle, the aluminum block, has  a fat resistor sticking in it with wires coming out left side.  Set screw is on bottom of block, also set screw for the thermistor.  You, or course have to remove the thumb screw thats holding the faceplate in place to drop the heating unit, barrel, block, and nozzel.
