IP Standard Cavities

[carloabarth]

Anybody know if standards exist for cavity sizes in the instrument panel for things like radios, A/C controls and such? And if so, where I can get a copy of said standards?

Radios used to be to a DIN standard, I don't know if that is still true. As far as I know EVERYTHING else is up for grabs

Cheers
