Switch Insert/Surround - Rocker to PushButton

I'm wanting to replace an ARB rocker switch the previous owner of my truck installed, and install a dual push button. Today I learned the rockers are larger and require the internal pushbutton switch mounting surfaces to be cut away, inside the dash. So, I tried installing the new push switch, and it just falls back into the dash.
Does anyone know of an insert to convert from the rocker type switch back to the OEM pushbutton style?
I didn't notice anything on CH4X4 or AirOnBoard.. They have rocker switch carriers, but not single pushbutton.. that I noticed, at least.

Thanks for any help.. I really need to use these dual switches. (I'm hoping to replace 4 rockers w/ two dual pushbuttons, so I can add a couple more switches)
