Along those same lines, it's interesting that the flex plate has 6 or 8 bolts to attach it to the crank but only 4 bolts attach the plate to the converter, and those bolts only have 4 or 5 threads. :BangHead:
The larger bolt pattern for the flex plate to torque converter gives you more leverage, so you don't need as big of bolts to hold it as opposed to the smaller bolt pattern of the crank to flex plate...
