Who figured how to install Cali splitter on a PP?

I've got a PP GT & would like to get the California Special splitter to go with the GT350 rear spoiler I have. Someone figured out how to get the splitter to work with the PP undertray. It was just a couple of cuts if I remember right.

Anyone know what thread? I can't find it using search. I'm not even sure what topic I saw it in.

There's an actual Ford part that will let you do this too.

Can this really be done?

Yes
Belly pan: FR3Z-17626-B
Splitter: GR3Z-17626-AA

The one I'm thinking of is the guy made a few cuts & used it with his PP bellypan.
