Can anyone please tell me the starting thickness and the minimum thickness (discard thickness) of a front OEM rotor on an 2007 H2?

I get conflicting info when I google. Some says 38mm new and 36.5mm discard, but that seems too narrow range. I can’t pull a wheel right now to check the rotor for a stamping, but need this info for when I caliper it for thickness. Have to turn or change out front rotors soon. Thanks.

 

 

Thanks for that info! Much appreciate it.
