Well he said he no longer has a column shifter so he never had the linkage for a floor shift. Makavelli, on a floor shift car there is linkage that runs under the car and up the firewall to actuate the column indicator, reverse lights, and neutral safetly switch. You could either find the linkage in a junkyard or use micro switches on the sifter wired up to the module on the column. I'm not sure which wires you splice into though.
