How many 1970 4 speed dodge TA challengers were made?

There's no single definitive number for how many 1970 Dodge Challenger T/As were made with a 4-speed transmission. Dodge didn't keep production records broken down to that level of detail (specific transmission type combined with model). Information on production numbers is usually categorized by model year and sometimes engine type, not transmission. To find an exact figure would require extensive research through original factory build sheets and other records, which are not publicly available in a consolidated form.
