Default MOFSET mounting on BOZ PCB

Hi,

I'm about to assemble a bride of zen from Nelson pass.

I'm a beginner (1st project), so I'll ask a beginner question :

I got a PCB, which you can see on N.Pass website:
http://www.passdiy.com/pdf/brideofzen.pdf

My problem is I don't know how to mount the MOFSETs because the drain is far from the source and gate. The drain also seems to have a bigger hole which I guess is for heatsink mounting.

How I am suppose to link the drain pin of the MOFSET to the PCB ?
What heatsink model is expected to be used ?

The MOFSET:

Thanks
Pierre

The drain is also connected to the tab of the mosfet. You put a screw through the tab of the mosfet and then the heatsink and screw it to the drain hole.

Maybe something like this for the heatsink.
