I can tell you about my disdain for spec if I see you this weekend (or you can search on here).

As for checking, You can check the 4 bolts on the flexplate (to see if they are loose or have a problem) through the inspection plate.

And (I'm sure you didn't do this but I'll put this in for others) you didn't oblong (or even redrill) the bolt holes on the flexplate because they weren't lining up? The bolt holes are that way because you can only put the clutch on one way (for balancing purposes).
