FYI, a small number of interface boards for the SA22 are available 
here:  www.ebay.com/itm/142461937901 .  If you look in the Designer's 
Reference & User's Guide, it shows the adapter board with and without 
the heat sink.  It has the same connector as the X72, but you don't have 
to use it!

It is on the bottom of the box where you want to mount the heatsink.   Not sure how one would mount it so that the full surface is on the heatsink.   It looks like they use a mating SMD PCB mounted connector.
