In this board I used a thick terminal pin to solder the Drain and Source legs of the FETS. This makes it simple to replace FETS without damage to the PCB in the event of a Failure. I did not install the optional small ferrite chokes.

The Pin I used is shown in the center of the PCB.





The Gates are connected via a 2.2 ohm (2R2) resistor, this makes it simple to remove the FETs if needed. These resistors is not shown on the circuit for clarity.
