Wire wheeled the fire wall and got rid of some rust and left over rubber gasket stuff from the heater, also got rid of some bubbly stuff that was caked all over the firewall, not too sure what it was.
Also, where the battery tray was on the core support had rotted out the bottom of it, is there a replacement patch for that, or is it something where I just find another or just make a little patch plate and weld it in?
