Firewall

Building up both sides of the firewall has been challenging.  There is lots of stuff on both sides.  The inside sheet metal was covered top to bottom with Thermo-tec heat and sound barrier. Also on the inside a new OEM Firewall pad was installed.  Multiple pieces of ducting, sheetmetal, defroster, air vent, heater, dampers,  and controls were installed and made operational. Screws and fasteners of all sorts were poked, pushed, pounded, threaded and cornholed into place from both sides. The octopus cable controls assembly was installed, as were multiple speed fan resisters, and thermo sensing temperature device for the heater.  The heater core was installed from the engine side. 

There was one screw from hell that cam from the engine side that gave us fits. In order to install this screw, which goes in from the engine side to hold the defrost damper and distributor ducting on the inner firewall, I needed to uninstall the distributor cap and rotor.  Once installed we realized the ducting was installed prematurely and the heater box compartment ducting needed to go in first. So the distributor and rotor was removed once again to assemble this jigsaw puzzle in the correct order.

A full day is planned for tomorrow, pegging the heater core into place, sealing things up, installing the heater blower fan, seals, screws, diffusers,  and whatnot to complete this portion of the project..

Attached are a few shots of todays work, more to follow.

 

Got some work done on the firewall. The heater core came in and out again. Some padding and a couple extra screws to keep things from rattling. Got the Heater Blower installed and hooked up. Lots of finishing touches with cables and mechanicals up under the dash.  This has to be tidy before wiring goes in. I nicknamed the Deluxe heater assembly the "Octopus" It's tentacles reach far and wide. It's a very ingenious mechanical ventilation and heater contraption, Brand new concept on a 57

Analog control, nothing digital here, well maybe the two speed fan control with associated resisters.
