I doubt it's worth your time or trouble. It's not a DIY job. You will have to have the third member removed (the large portion between the driveshaft and the entire axle), have the ring gear swapped from the old open diff housing to the new LSD housing, and have the ring and pinion adjusted for proper backlash etc. The backlash adjustment is precise tedious and not something that you want to screw up. Anyone will tell you unless you know exactly what you're doing, have a professional do it. It will run you several hundred bucks for labor.
