HEATER CORE REMOVAL

Heater problem

How do you seperate the heater box from the firewall. I've removed the hoses, and the one 10mm nut on the ext. Side of firewall and 10mm bolt from bottom of heater box on the inside. The heater box still feels tight. Is there hidden bolts or does the evap. Box on the exterior side have to be removed. Any help would be great. Thanks
