Early "B" body 4 piston disk rotors

[bitterbelvedere]

I recently bought a pair of used rotors for the 66-69 4 piston disk brakes. They are smooth and not scored so I'm going to use them regardless as these are difficult to obtain. I was curious as to their condition thickness wise. Does anyone have an old brake book with the minium thickness for these in it? Anyone have an NOS one they could measure for "new" thickness? With so many rotors being remade now has anyone reproduced these? Any help greatly appreciated.

From the '68 FSM

Bendix - Thickness = .868" - .878" Minimum = .816"

Kelsey Hayes - Thickness = .810" No minimum specified on specs page

Thanks Histoy. For some reason the forum did not alert me via email that you had responded.
