A903 - no floor shift?

Don't know, but "back in the day" there were PLENTY of aftermarket "conversion" floor shifters, made at the bottom end by no- name junk, JC Whitney, and up to the upper end--- Fenton, Hurst, and others. There were several in my town, growing up, including one of my cars, used a Hurst "Mystery" shifter

These were all designed to convert a column shift vehicle to a "better shifting" floor shift
