Help, Creating dc motor symbol for LtSpice

I'm trying to model a dc motor and would like to convert the example
found at:
http://www.ecircuitcenter.com/Circuits/dc_motor_model/DCmotor_model.htm
to a ltspice symbol and subcircuit.

My goal is to have a symbol with two pins pos and neg as would be on a
motor. I know the V_AMP would have to be removed.
I'm very new to spice and don't know what steps i need to take to do
this.
Any help is appreciated.
thanks
jim
