Hemi 4 Speed?

Sounds like a slick shift mod that requires everyother tooth to be cut off. I don't kow much about the mod itself, but I never heard of the syncro's being messed with.

As far as a "'historically significant" unit, as far as I can see, no except the date codse to the trans may be helpful for someone restoring a car.

Is/was this car a factory built HEMI car? If so, that trans will belong to that car itself.
