Ok guys I have been reading this thread and it is now time for me to speak up. I have, hands down, the best shift knob in the entire world. It was fabricated from NASA grade tungsten for use on compressors on the space station to convert carbon dioxide into drinking water. My boy made it and had it on his ride, but I made an offer on it and he sold it to me. Not only is it a unique knob shifter (the only one) but it is a conversation piece. Not only that but it doesn't weigh 300 grams. It doesn't weigh 400 grams. It doesn't weigh 500 grams. IT IS 6 GRAMS SHORT OF 800! A WHOPPING 794 GRAMS! It is almost two pounds and if I needed to, I could unscrew it and put it in my fist and call myself the one hitter quitter. It is that solid.
