I think thosre are the "original" Dura Ace SPD pedals.
Do you only want NOS, or are good used (14,969 miles, with original box and instructions) o.k.? I took them out of service only because I switched to Time RXS to get lower stack height and weight.
I don't really want to go to post office counter service during the pandemic to mail them, though.
Choice of SH-71 cleat with float or SH-70 cleat with no float.
Well, I really messed things up. I was checking that the release tension adjusting bolts were still operational. In the process, I must have loosened the left pedal relase tension bolt too much, and a little black piece fell off and I can't find it.
