eeven if the thread is wrong, you could tap it or use a grub screw through a small threaded hole to hold. Its alway nice when your knob looks good 
right you are mate. just hate to spend the coin on a TT knob and have to drill it. Thinking about lopping an inch off the shifter anyway so i could recut it to anything i wanted to.
only thing better that having a nice looking knob is getting it polished up.
