Heater and radio delete on a 69 dart?

Made my own heater delete plate for the firewall but Mancini offers one now

a few pics I've collected....

First pic is the one I made, second is a shot of a factory heater delete fresh air box on the right side which replaces the one built in the heater, third is factory firewall plate that I was given the dimensions of 6-1/2" round and 6" to the flat side, and the fourth is a factory heater delete 69 dart in Hawaii from a FABO member

Also do a search on this subject with the FABO search function you will pick up a lot as this isn't the first time this has come up.
