From what I have been able to figure out, the one on the left, with the L at the bottom is a 64/6. The one on the right with the L up higher is a 67. Remember 67 has a different shifter, I call it a pocket shifter, this was used to clear the T400, but used on T 300 also. I currently have a 65 GS with the original shifter in it and it is like the one on the left, L at the bottom. I also had a 66 and it was like the 65. I have complete 67 shifter/console that I am going to sell and it is like the other one.
