Does anyone know what the alloy of the aluminum side body panel is? The assembly manual does not seem to list it, and I wouldn't expect it to. Is there a spec anyone knows of? 6061, 3030, or what? I am looking at changing from the plastic fridge access panel to the smaller aluminum one and will need to weld in a transition piece. I can measure the thickness of the body (it measures at 0.062" average in that area).

Found this on GMCnet: "I'm not sure of the alloy but the aluminum is .063 thick. I suspect it is 5052."
Check out the whole thread for some interesting observations about welding the sheet panels (not recommended): https://groups.google.com/g/gmcnet-archive/c/VplfMD9k0nk/m/BZBaDEGfCAAJ

I thought I would share with the group that the alloy of my 1978 Eleganza II body skin was tested by one of my company’s Level 3 NDE technicians using a Niton fluorescence X-Ray gun.
The skin’s alloy is AA 6063. It is not a 5000 series as previously thought. Also, the gun cannot tell the temper of the alloy.
An interesting note is that alloy is considered very weldable. But being 1/16” thick (0.063”), probably will warp.
