hood mounted tach

there was not a "factory" hood tach. they were all either "dealer " added or personally installed and ordered through "hustle stuff" .the factory never offered those as an option therefore there is not a "specific" location
Now that's the first answer that needs to be examined! And the best one! I would kind of think that again this would lead back to put it where you want it? I never considered it an option as I always thought it was something like that came on a GTO? Not to say I didn't think it was cool and not to say I wouldn't want one...
I don't recall ever seeing one being stock on a Mopar?
