Has any one seen a later DC (red sticker) version without the pin/slot? A set used on a 83-84 bike with low original miles perhaps. That will take us even closer to eliminating a distinction between the DC and GC versions, i.e. the purpose of this thread.
My set of NOS GC 610's should be arriving in a couple of days so I'll have another pair to check the pin/slot situation on. Sadly this item is rarely photographed in ads or on bikes to allow seeing that pin. The natural is to do a front and rear photo, as who cares about a top down view.
Keep the observations and questions coming folks. The overall picture is getting clearer everyday.
