Throwout bearing self aligning or standard

I got my Mcleod clutch, pressure plate, and throw out bearing from Brewsters transmission (Mopar trans only) and they never asked me that question .... now I'm wondering what I have on my car now. lol

I'm sure if it was a big deal they would have mentioned it wouldn't you think?

I agree, its really just my own curiosity. What normally goes bad first? the bearing or the clutch?? I drove the bjesus out of my old ranger..replaced the clutch and bearing but only because the clutch was toast..clutch was going again before I sold it but the bearing was holding up just fine
