to resume
you have the choice to find identical pinouts ... if they still exists
find pcb adapters / converters, to mimick the old pinouts with new modern caps
to cut them open, and fit more recent in them, to keep the look ...
and yes thoses who used the casing pins to transfert traces / conductors dang messy situations when you forget that "small detail"
had problems in Fluke equipment's because of that "small detail", took me a while to remember that
