My 9A has a 6000/7000 .
9A of 68 or 69?
Do you know the date on the back of it? I thought they had switched to the 6000/8000 well before Sept??
My 09C car has an 8K tach; date on the back of it is '197 69' which corresponds to July 16, 1969. This is consistent with most other parts on my car, except for a few dated almost immediately in front of the engine assembly... see photos.
ps. I also noticed there's a label on the instrument cluster itself with large NN code (any idea what this is for?).. along with a speedo pn, and tach (with hand note - illegible unless it might be '8')??
