Trust issues

This is exactly why I have a hard time believing anything I read or see. And this is why i ask alot of questions to the ones who have done these things and not just read about them. I know for a fact that the thrust plate has the slot facing inward when I took it apart. I have three books I reference one says to face the plate the correct way the other book clearly had it in backwards. Had I not already known or didnt own the other book I probably would have put on backwards. I wonder how many people have incorrectly assembled this part based on this particular book?
