So I got my twm short shifter and shifter base bushings today and I installed the short shifter no problem. When it came time to put in the shifter base bushings I removed one first to check fitting, the bushings are appx 19.7mm and the hole in the shifter base is appx 18.1mm. Arent the bushings supposed to fit into the holes in the shifter base? Could someone help shed a little light for me.
