Re: Early '63 rev limit warning alarm???
I think the part number on the back of the buzzer cluster case is 6406122. The one on the non-buzzer is 6405757. I just looked at a late low-horse cluster with a 6405757 case. It does not have the hole for the buzzer tach lead.
If you are correct that all high-horse cars originally had buzzer tachs, Joe, then cars that now have high-horse tachs, but, have no hole and/or p/n 6405757 stamped on the back, are probably ones that have been converted from low-horse cars. But, maybe not....
