I just installed the TCI ratchet shifter for the 2011 in my 2006 they are the same aside from the length of the shifter bezel.
I used my old one that I was taking out, they fit the new TCI shifter. All you have to do is unsnap your old bezel unsnap TCI bezel switch indicator tape from the TCI with your old one the and snap it on the TCI shifter and you have a perfect fit!!

Here is what it looks like done.

 

Just curious if the shifter is still working well? I'm considering doing it to my 2005 Mustang GT.
