Which 66 Mustangs came with the disc-brake option?

I trying to find production numbers for the mustangs that came with disc brakes and would also like to know if it was only available on the GTs or if it came on regular mustangs. I have an A code fastback without the GT setup. Did cars like mine ever come with discs??

as i recall all V8 mustangs had disc brakes as an option.

Yes, disc brakes were an option on all V8 Mustangs. Some people assume, incorrectly, that because they have disc brakes that they have a GT but that is not the case. Very few early cars were equiped with factory discs.
