I keep breaking the rear end in my mt82 car

So, I have a 2013 5.0 with the mt82. I have a an exedy stage 3 clutch, basic bolt ons, and I have been running a 28x10x15 MT ET pro when it's "track time". I know that I should have been running bias-ply slicks with it being a stick car, but those radials were the tires I had, and I wanted to use them up before I got bias-plys.

The first time I broke the spider gears in the rear end, and I replaced them. Second time I broke them again, so I put a mini spool locker in it. I did't like the way it drove with the mini spool, however it seemed to be effective. The 3rd time I twisted an axle tube and I've had to replace the whole rear end. With the new Rear end I've already had the tubes welded to avoid the twisting problem again, and I haven't put the mini spool in yet because I'm hoping that switching to a bias ply tire will help absorb that shock from those 4500+ rpm launches on a prepped surface.

So the question is, what else can I do to keep from breaking the rear end? No i'm not going to lower my launch rpms, if whatever surface I'm racing on is sticky enough to to send it, I'm going to send it. I'm almost to the poing of trading back to an auto 5.0 just to avoid the shock that a stick car has on the launch, however I am very fast with a stick car and I love racing one. So you guys let me know what I can do to avoid down time from something as simple as a rear end, I'm tired of hearing "haha your POS ford broke"
