Well since it's been raining here for like 2 weeks I needed to do something . So I grabbed a hunk of black walnut and made a the shift knob that was missing on my truck. The I used some maple for my wife's truck. I got the rough shape on both with an angle grinder with a sanding disc . Drilled and then I JB welded a nut in the wood and JB welded a corresponding bolt into a socket then used the drill to turn and shape with sandpapers.
