Kelsey Hayes rotors

I recently acquired a 1972 Dart that has the 4-piston Kelsey Hayes brakes. I'm wondering where I can get replacement rotors. Everything I've seen online is for the slightly older style with a separate hub that the rotor attaches to. This car has unicast rotors; no removable hub. Do replacements exist? Or am I just going to have to get the ones on the car turned? Thank you.20240630_170442.jpg
