i can see why you blew up the oem diff. i dont think the open one is going to be much help though. i have a auburn limited slip that has stood up to some abuse, but my car is pretty light. you may want to get one of the mechanical types

Yes, I agree for sure. I will be keeping an eye out. I am also currently working on my police interceptor daily driver so money is tight right now but down the road I can see a 4l80e or fully built trans in addition to the rear end

the 10 bolt might be fine for a while with 3.42 gears and a open rear. i have a ten bolt but its got the main cap support, better axles, and 4.10 gears and the eaton limited slip. ive got a whole bunch of strip launches on it. a bunch of people run ten bolts, and turbos are a bit easier on drivetrain stuff too
