I just swapped a super turbine 300 for a TH350 in a 67 firebird. Everything went great! Now my problem is I have a column shift and want a floor shift, The shifter I have Is a chrome t handle with a black top I believe its a 2 speed shifter, Is it possible to file a dent into it or is there another out there that would fit and work properly? I might add it is a rod set up not cable>
