It seems that some tachometers have the redline and others do not. Was it a mid-year change like the recessed rear quarter panel reflectors? Was the redline only on later built cars? (Maybe it was added mid-year to cut down on warranty repairs!)
Correct, some are redline, some are not.I havent studied them to see if its date specific?

There were also some cars with 6,000 rpm tachs so maybe it is just a supply issue?
# 459 built Dec.9/67 knee pad and 8000 tch with red line.

To restate other reply's the redline no redline was apparently random in 67 which all had knee pads but the redline or no redline tach had no apparent pattern of usage in 67 . Both were used from the factory in 67. That seems to contradict a early late hypothesis .The somewhat no pattern usage seemed to have continued to be so in 68 also.

I did read and I am not ignoring those replies. 1968 was a completely different situation due to the strike and the change in GT Mustang tachs from 1967 to 1968. Also, many tachs on restored cars have had the redline added by Shelby "experts" who believed the redline had faded away or the non-redline tach was incorrect, which of course is wrong, but which makes it more difficult to date a production change. For 1968, it seems that a running production change was likely, with the earlier cars having no redline.

Help me understand what you perceive as the main difference between 67 and 68 tachs. Thank you in advance for explaining your point of view.

Thank you in advance for explaining your point of view.I suggest that you research 1967 and 1968 Mustang tachs and the GT option. We still may have a difference of opinion, but that is fine.
