I guess by DID you mean DynaDrive, the oversized pedal with the single inboard bearing? My Deore arms are DynaDrive, and AFAIK all original Deore arms were. I have the matching Deore DD pedals. AFAIK any original model Deore arms with conventional pedals would use an adapter that screwed into the oversized DD hole. I have at least one pair of those, but can't imagine using them, as DD, regardless of technical merit, was certainly an interesting innovation.
