The back glass base (shown below) is in poor condition and I'd like to dismount the back glass, wood fill the cavities and paint to match. I was wondering if it's OK to put a back box on it's back when I do this work. I don't know if I need to do anything special to secure anything (other than the existing steel harness). I'd appreciate any advice?
Also, does anyone have the Pantone color numbers for a '76 Gottleib Surfer?
