Resin shift knobs in black, green, or purple. You will need to drill and tap them. $30 plus the cheapest postage to your door. check out my website and tell me which color in your note http://www.monsterequipped.com . I have some that are paintable as well for $20 but they aren't nearly as fun. These are not mass produced and so the occasional blemish or small bubble is possible... Just think of them as unique If these sell i will make more colors like red, blue and yellow.
