Instrument glass size

[Tlupo]

I’m hoping to order new glass or acrylic prior to removing the instrument gauges In my 1982 3.3l 911 Turbo (930). What are the correct sizes of the glass for each instrument panel gauge? Also any recommendations on where to order would be appreciated.

Pelican sells replacement glass for gauges.
A glass shop can also cut circles, thickness varies so if you have it custom cut it’s best to have the old plastic ones available for them to size it.
