I have seen quite a few column shift 440 Six Pack and Hemi powered cars... I would estimate 15-20%
My FY1 Cuda 440-6 is a column shift car, as is my Hemi Charger R/T, 440 Six Pack Charger R/T, and an AAR Cuda that I used to own. I also have friends with original column shift cars like a Hemi Cuda, Cuda 440-6, etc.
Several that I know of have been converted to console shifters after the owners decided the column shifter did not fit the car's image...
