I have a 2011 LS3 with Hurst Short Throw Shifter. I want to change the shift knob every once in a while and am wondering if it is a pain to change. I saw a video and all the guy did wash pull off the surrounding plastic, unscrew 4 screws and the he pulled the shifter straight up. I always thought it screwed on or something but I guess I was wrong. I also want to get this shifter if anyone know what website it is off of:
