I plan to install a S15 helical lsd in my R200 diff but I need to also fit the diff stubshafts which are the 3x2 pattern. To do this I will need to shorten the existing driveshafts by approx 35mm. The easy and expensive option is custom drive shafts incl a change to cv’s. The cheap option is to make an adapter to mount the existing yokes to the new 3x2 flange and shorten the spline on the driveshaft by 30mm or so. As all the drive shaft balls and spacers remain in place and the sleeve yoke remains full length I reckon this will work. Has anyone tried shortening and was it successful?
