I did swaped my powergilde for a TH350 and changed to floor shift on my 68 a couple months ago. You'll need the shifter cable, the shifting brackets, the kickdown cable and the kick down bracket which goes on your carb. You can get all of these things from shiftworks (www.shiftworks.com I think) When your done hooking up the tranny, make sure you hook up the safety neutral switch. It took me a while on mine to figure out that that was why my engine wouln't start.
