I have a surplus R180 LSD, 4.11:1 ratio, it has a viscous centre. All in good condition, measures up great for backlash (0.005 inch) and runout (0.001 inch) on the crownwheel. I'll never use the ratio so out it goes. I reckon its worth around $400. If interested, e-mail ben@digsfish.com or 0403773592. Its in Brisbane.
