I have the MKIV carbon fiber dash (no glove box) and the Vintage Air Heater/Defrost unit. The Vintage Air kit did not come with any installation instructions or template for recommended firewall cut-out. Does anyone have anything they can share? Rough plan was to put it in the location where the glove box would normally go. I'm also going with a Coyote Gen III. And this is my first build, so any tips for the heater install would be appreciated, too.

Thanks!
