Rough diagram of what I'm planning - reuse (or replace) OEM dash bar, attach footers to the floorpan, add removable door bars for added side impact protection.
Some of the Lotus 7 guys use these plug in defrosters - I'm worried about its ability to clear a whole Miata windshield, and it wouldn't provide any heat.
Aftermarket heater/defroster sold at Summit Racing (approx $140, 9lbs weight, reuses OEM coolant line) - has two built in ducts, I plan to use one for defroster and one for footwell heat.
Example of a cut down dash - I'm going for something like this but will retain the center stack for radio, aftermarket heater control, power window controls, etc.
OEM dash components including dash bar and HVAC ducting.
OEM HVAC components - center stack (5lbs), AC unit (6lbs) and fan unit (4lbs).
How the car looks with the OEM HVAC parts removed - paper towel is soaking up some spilled coolant.
Note how the HVAC ducting kind of wraps around the OEM dash bar. The OEM dash bar is very thin so I didn't want to reuse it, but it also has alot of complex bends so replacing it requires removing most of the HVAC ducting.
I think this is part of the airbag system, if so I will remove it.
Same thing here - airbag component? This was mounted front top center of firewall.
Stock dash bar mounting point - note the bar is only held on by 2 bolts on either side...
Another view of stock dash bar mounting point.
View of the OEM dash bar mounting from the inside. Note the dash bar is cut - we are going to reuse the side brackets.
Main door wiring harness - harness into door panel has four wires, two for the speakers (speaker connector can be seen hanging out lower right) and two for the power window regulators.
Center console wiring - big connector is for the power window switch, I honestly have no idea what the little white one or the one with the metal bracket are for. This wiring is attached directly to the main wiring console that runs behind the dash.
Showing how the power window switch plugs in.
What a lovely sight - the main dash wiring harness, all jumbled up on my windshield right where it belongs....
