1968-79 Chevy Corvette Heater Box Exploded Diagram - Core, Inner/Outer Box

This document is a scanned exploded parts diagram labeled "68-79 Heater Box," showing the heater box assembly for 1968–1979 Chevrolet Corvette models. The line drawing depicts the heater assembly in exploded view with four labeled components: the Outer Box (the housing on the left side with the blower motor mounting area), the Inner Box (the larger housing section on the right), the Heater Core (the finned core with inlet/outlet tubes positioned between the two box halves), and the Lower Outlet (the ducting piece at the bottom right of the inner box). Several fasteners (screws/nuts) are illustrated around the assembly showing where the components bolt together, though no torque values or part numbers are given. A reader can learn how the heater box halves, heater core, and lower outlet duct fit together, which is useful when disassembling the box to replace a leaking heater core or reassembling the HVAC housing during restoration. The diagram is part of a larger album of Corvette reference scans covering various chassis, body, and interior systems. No part numbers, dimensions, or written instructions are included—the document is purely an illustrated component-identification and assembly-orientation reference.
