Hi. I got hold of a GT/Rallye Instrument Cluster for the 75-80 240's dashboard (which includes my '75 164), but it included the 4-cyl. tachometer (obviously, I need the 6-cyl. version, but that's even rarer!).
I've learned that in the later years when these sets of instruments were sold, they had a different tach, one that had a dual input, "F" for a 4-cyl. input, and "S" for a 6-cyl. input.
Needless to say, while I'd love to buy one from someone, or swap them for my 4-cyl. tach, what I could really use is simply the part no. for that tach! If anyone has access to a fiche that shows the part nos (I guess, any ~'78 to '80 240 parts fiche, at the instrument panel blow ups), I would appreciate being informed what the part no. is for this dual-input tach.
Thanks.
