4th Gen F-Body Rear Rotors vs C5 vs C6 base

I did a fair bit of reading on brake upgrades last year and just wanted to verify one thing before placing an order for new rotors.
4th gens easily accept C5 or C6 calipers with a simple bracket & brake line change and after that either C5 or C6 base 12.8" diameter rotors are interchangeable for the front, correct? ( I believe the specs look the same for diameter and thickness, except nowhere can I find anything about offset or hat depth)

Now for the rear (which I am only doing because my current calipers are pretty worn & because I grabbed a full car set of C6 calipers off a Very low mile vette) It appears that all three cars I've referenced again use the same diameter and thickness of rotor, but again, no one mentions offset/hat depth...whatever the term is that I should be using)
Are the rear rotors off of all three interchangeable?
If not, do I want to stay with the 4th gen f-body rear rotor or go to the C6 rear rotor, once I bolt on the C6 caliper (which as far as I remember reading, should bolt right up with no bracket or other mods)

You may want to look into the interchangeability of the master cylinder to make sure everything works correctly.

I have not seen the master cyclinder mentioned as a problem in any of the readings that I have done when swapping f-body for C5 or C6 base calipers

It is not an issue. I have CTS-V 4 pistons up front and there is no issue. Not sure about the base but the c6 z06 calipers require brackets for the rear.
