Thank you, Charlie. I finally found this spec somewhere online last night, (same answer, 42nm), I know that this tightening torque is pretty important. Too loose and they could unscrew, too tight and could fracture the screws or the flex plate.

I also read that these bolts should have a flat washer plus the wavy/lock washer on each one and maybe some blue Loctite. Mine only have the wavy washers now so I am going to get the flat ones from dealer and re-install them soon w/ Loctite. Might as well do them right, they're easy enough to get to. Thanks again!
