A or F body Hurst 4 Speed Shifter.

Someone correct me if wrong, but that hurst box indicates it is used behind A833 OD, Not a tree speed unit... and the handle is an F body???? And would not this same unit been used in Feather Duster of '76 with the same A833 OD ?????/ or other dusters with A833 OD?
Does seem like there has been some conversation here deleted????.
