firewall

[American_Muscle]

I'm looking to replace my air conditioning box with a non A/C unit, but the firewall is different, anyone have a firewall out of a non a/c car they'd want to part with? or is there a way to fab it up and patch the old holes.

You can even look for one from a satelliet/roadrunner or charger from 73/73, both makes.  I know Charger1973 is wanting to do this as well.

Yeah I would like to do this to mine but all of the cars ive had in the last few years have been A/C cars.  I do know where there is a non AC 74 Satellite sitting and have plans to snag that section and the heater box, if not the whole car sometime...

Cut out pieces of sheet metal same as the holes you want to fill and weld it. I did it on my 69, here is a pic, it used to be a A/C firewall.

Harder to cut out areas on a 3rd Gen car.........the seam between the cowel and firewall run right along the booster mount area if its rusted badly....but if not rusted too bad then you can go ahead and try and patch...
