A75 cooling issue

[ChrisS]

Hi everyone, I'm new here and could use a little help.

I have a '46 7AC with the STC for an A75 upgrade. Im having some cooling issues and it doesnt look like the HELPS & HINTS #26 - ALTERATION #1 per the STC were done.
The nose bowl cutouts in drawing S-16 is easy but, I cant quite see what the lower cowl cutouts etc looks like. I have all the applicable drawings.

Does anyone have picture of this alteration on their plane that they could share with me before I start cutting up the cowl and the firewall?

Thanks,
Chris

Chris, in the two attached photos you can see the modifications suggested. I hope these are helpful.
