It did use the Y77. The Y89 is what I believe to be one of the replacements for the Y77 and may have been a production line battery for later/different models? The Y77 had two different size terminals. The Y89 is a standard 3/8-16 terminal size battery. The negative battery cable or bolt had to be changed when the Y77 was no longer available. I think the Y89 came out around 1974? The Y77 was a one year only battery. Very rare.
