Hi everyone. Iím new here and this is my first post. So I have a 68 GTO that Iím rebuilding with a column shift transmission, TH400 with a shift kit and 2500 stall. They ignition is in the dash. Iíve been looking around for the linkage that I need and all Iíve been seeing for it are for 69-72. I have the long rod that comes down from the column but nothing else. Ames performance, summit, year one, all show 69-72. Nothing for a 68. So my question is, would I be able to use the 69-72 kit on my 68? Whatís the difference?
