Rotor thickness minimum 4-piston KH?

FSM says to not turn them mostly cause in 1968 the factory had little confidence in the lathes then in use to maintain run-out and thickness. Today they are taking them down to .750

Today they are taking them down to .750
Not true.
Where did you come up with that figure anyway????
.790 is the minimum.
Always has been, always will be.
That will be one paper thin rotor, at that specification.
Don't go posting inaccurate information.
Whose "They" are taking them down to .750 anyway????
