1970 charger firewall

Hi, could someone tell me what pieces goes here, cause i saw others chargers and are flat, if you can send me a picture a appreciate so much
thanks

A/C firewall:

lower left: blower motor for heater/aircon

upper right: heater lines from engine and water valve

hows this... and that's an A/C car. I mounted the EMC over the old heater control valve area. Note that this car does not have a heater/AC box, it's just made to look like one.

You can see here that I changed my air condition firewall to a non A/C firewall.

ok thanks, I think I'm gonna put a mark IV, the blower motor hole don't use anymore? just the lines hoses, right?
