From reading a lot of the posts on this great site I see that a few of you have replaced the various heater control knobs,cruise control,headlight knob,and window buttons with the billit aluminum ones. I have ordered these from Haney Motorsports in Ca. ,but they haven't arrived yet. I was wondering just how hard it is to remove them,without damaging the old parts,and if there are any special things that I should know about installing the new ones. Any tips would really be appreciated. Black Bullitt #1768
