lol. first one is just a saturn diff with welded pin - takes a bit extra effort to blow up. The second is a beautiful and somewhat rare quaife, I do not know of the diff ever blowing but yes the rest of the trans is still vulnerable. Although the trans only has 40,000 miles on it!
Sam is running well over 20 psi on his turd and no issues on the diff. Clutch and blockers another story.. he said that his blockers for 1-3 and cracked or broken and it wont stay in 3rd on its own sometimes lol.
I will have to keep you away from my turd I do not want this one to blow up! But I will have to lay down some two wheel burn outs with it maybe let you try it out if you promise not to break it.
