Here are the mechanical parts for the G-SSL bus compressor (from the SSL 4000 console)

You can choose between the blackface version with toggle switches or a more original looking frontpanel with illuminated push switches. (which are available here)
Different rearpanels are available... a blank rearpanel with no holes (so you have to drill the xlr and iec holes yourselfs - and save some money) or buy an already cutted rearpanel with cutouts - much easier!. ;-)
