What gauge metal did you use? Did you have to tack weld to the Redondo brackets? did you have to use a metal brake? what do the brackets you made look like. where they just heavy duty straps? I will make this work. I can't afford those retrofits. They are about $700 Bucks. This car is in all original condition so I don't want to modify the dash. Another issue is I do not have a complete Radio only the front face, no housing to mount electronics.
