Again, we are just using it as a spring and CP level or calibration should not be an issue.

Depending on the stepper motor and the amount of purchase/leverage you design into its connection, you may or may not even need any spring on the bottom side.

By leaving as much OE stuff in place like not modding the Plunger or removing the WUR, it makes the conversion just a bit simpler and keeps it easer should one want to go back to stock.
