As some of you know we were part of a product development with Mfactory. The whole point of this was to bring the R200 more helical LSD options. This production was a great success with the help of great members of this community. The original thread is here. They are currently for long nose R200s with 10mm and 12mm Ring gear bolts. Accepts 29 spline stub axle shafts.
