Upgrading from kelsey hayes to???

Wondering if anyone has or knows about mounts to put late model viper or brembo calipers onto a 72 demon that already has the kelsey hayes disk brakes, ive searched everywhere but it always leads back to swapping from drum to disk and im hoping to keep all my 72 sbp front end parts and just upgrade to better calipers, also I have access to a milling machine so making my own brackets is an option, really just need to find the best caliper for the job and was hoping someone has done this before..

Thank you in advance
