I did tons of research and decided that the Powertrax Lock Right was the most durable. It clicks when you turn, but oh well. Justa350 is running the same locker.. I run this on my GS 350 that is a drive anywhere out to dinner take it to the strip and spray it car. F the limited slip stuff. Get a locker. There is no clutch material to wear..
Nick, I'm running a stock posi carrier that I got from Monzaz on this board. Check with him, he may be able to hook you up with a good deal on another or repair yours for a reasonable price. If you get yours rebuilt, go with the 800 lb springs. If you want to get up and running, I have an 8.5 open carrier you can have if you want to come and pick it up.
