I'm hopping on here from the TJ forum hoping you can help me. I am looking for an adaptor that I can push down on the knob so i can use button-less aftermarket knobs on my 2004 auto shift. Many companies sell JK adaptors but not TJ. The shaft size in the TJ is 16mm. I suspect the JK maybe the same and that a JK adaptor such as the Lo-dapt would work. Can someone take an open end wrench and verify the size? I don't need a precise caliper measurement. Thanks.
