GAPCO: Vintage Pressed Steel Enclosure

I'm sure we're all familiar with these enclosures from GapCo, just jotting down some notes for myself, as I found a drawing with dimensions (sorry Reverb seller).   

GAPCO VINTAGE ENCLOSURE

• Plain unfinished steel, arrives lightly oiled, may have light rust (will need a very good clean)

• Holes for pots are 6mm, which suits 16mm pots

• Note that these enclosures come without screws, and they are also untapped (the thread for the screws need to be cut in). 

HARDWARE REQUIRED

If ordering direct from Gapco, they are not supplied with screws - #8 x 1/2" Pan Head Phillips Sheet Metal Screws.  Alternatively, get the nearest size stainless steel metric self tappers from Bunnings.
