Quoted from G-P-E:replaced them with a new series which has all new keying
Can you dremel out the keying and the spacing is still the same? No key would be better than no connector.
Next time there a show with a decent flea market I'll have to look into the boxes that some of the junk collectors bring for wire harnesses to harvest these parts off of. At some point the repro board makers should consider adding in alternate connectors so new harnesses can be built.
