Have the gearbox out and the flex plate is split all the way round. See picture.
Question: Does anyone know the torque figure for (a) the four bolts that secure the flex plate to the flywheel spigot and (b) the four bolts that secure the flex plate to the torque converter.
I have heard that a revised figure was introduced?? car is year 2000 4.6V8 Auto.

A revised torque figure wouldn't make any difference to a torn flexplate like that. imho.
Just fit a new plate and do the bolts up tight (with threadlock).

The failure of the flex plate is probably a combination of age (over 100k) and the fact that when it was removed there was no buttress plate fitted!
I always follow the book when it comes to torque values on bolts, especially those I don't want to come loose or let go. Just "do the bolts up tigh" is poor practice. Locktight yes.
The book indicates 45nM but I have been told of an updated figure of 60nM. Does this apply to my car?? Anyone with real knowledge please help.

40+ years as a time served commercial vehicle mechanic and plant mechanic, is my knowledge, trade and living.
Does your manual state a different torque figure for dry and lubricated bolts as well (also does it state which grade of thread lock to use)???
How long have you been messing with motor cars???
How many total engine, gearbox and a diff rebuilds have you done in the last 40+ years??????????
And has your torque wrench calibration been tested within the last 12 months???

And you still say just "do up tight with some threadlock" !!! I think doing them up tight to the correct torque is the way to go and pray you never work on my car! Look the book says 45nM plus medium strength Locktight - BUT I have been told there is or was perhaps a TSB that revises it to 60nM I was hoping that someone can verify?
ps just found this:

There you go, wouldn't want you to get the wrong grade of locktight, would we...it would effect the torque spec/holding capacity.
threadlocker info
If all else fails try a large blob of agricultural locknut, doesn't tend to come undone easily...:scratching_chin:
