*Raises hand* Sploded the diff in my FD as well. I ran a TII diff until my car got crushed. Easy swap. If the LSD doesn't have the spider gear debris to jamb the entire diff and flex the case until it splodes, then you can get away with the stock case. Yes, the case isn't reinforced but has a much better record with a clutch type LSD. then you just have to make sure you control wheel hop.
If you end up going with a TII LSD, I have a set of solid urethane diff mounts, already installed in the dog-bone mounting bracket, I'll sell you cheap.
I've swapped 4 or 5 diffs on my back in a garage. Not too bad except the bolts and Fuel filter on top of the differential.....unless you are a contortionist who owns Gearwrenches!
