Regards from México A body fan and owner

Yes 340butterduster, that hood tach is a factory installed equipment, all Super Bee`s here in México had that one as standard equipment since 1970, except for 1971 cars only which had the rally cluster with the tach in the middle of it.
That super bee name continued with the F body Valiants until 1980, but these ones didn`t have the hood tach or any tach for that matter.
One oher thing, these cars are not USA exports, those were assembled here in México, at the Toluca assembly plant which currently builds PT Cruisers (for some more months only) and the Dodge Journey.
