3 and 5 gauge pod

Hi all. i have purchased a 5 gauge pod, but i am missing the switch OR blank that goes where the suspension switch goes in the Bottom Right Hand Corner.

I have the Part No: SV 12F 060607 which i got off of a forum.

Where can i purchase this part from. Having a lot of problems trying to find them.

Any help would be appreciated.
