Review on Dewhel Custom Aluminum Universal Shift Knob Shifter Adapter: Compatible with Non-Threaded Shifters for BMW Mini M12X1.25 (Black) – Enhanced Performance and Style by Jay Brock

So before ordering, I measured the shift thrust in my 2014 Wrangler. I used a socket wrench to find the right size. The 14mm jack went in easily and conveniently. I decided to order this adapter for 14.3mm just to make sure it would work without any issues. I was very disappointed when it arrived and didn't want to continue. With time and effort we drilled the hole slightly larger to fit.
