Rotors available (for now) for K-H disc brake cars

Just came across this. I'm in the middle of installing the rotors I had pressed onto the hubs a couple years ago. Bought them from Rock Auto in June 2020, Bendix PRT1054. Having the same problem with caliper dust boots rubbing the hat, and the bottom tip of the calipers rubbing as well. Not happy, just assumed they would fit, but there's really no telling until it's all put together. Rock Auto doesn't even list the rotors. I still have the original rotors, they measure about .765 and are rusty. Better to find out now, body is still in the shop. I will be watching this thread, hoping for a reasonable solution.
