Real nice upgrade for the interior and goes great with the boss shift knob but real annoying to take the old one out if you have big hands(old one is obliterated and has some blood streaks on the back of it, took around 45 minutes all together). As for the install, on the plastic ring at the neck of the boot you have to cut off the tab. Also not sure if this was because of the Barton shifter or not but I had to shave some of plastic rings insides out to get it around the shifter after the threads.
