Inserting the shifter into the base with the new retaining cup. With the stiff new spring, it was easier to do this on the bench. I also made a slight design change to the B&M shifter, it comes with 2 short (6mm) set screws to hold the ball to the shifter, one behind the other. I found that in use, the inner screw worked loose (not enough threads holding it in place) and the shifter was sloppy. I replaced the two short screws with one long (12mm) screw and this solved the problem. Replacement screws are available, e-mail: sales@4Crawler.com for more info..   (4/8)
