I don't sweat much the future availability of the rotors from aftermarket. There's many trucks out there with the same rotors on them for the last 35 years. How often do you tear up rotors and need to replace them ? Not very often for me.

Cheyenne Shortstep, you spoke of having had difficulty with kits in the past. I've done a good number of the conversions using the ECE kit and never, ever had any issues at all. Their kit includes every single thing you need but wheel bearing grease and a bottle of brake fluid. No mods, no muss, no fuss. Literally, remove drum brakes, install ECE disc brakes in a couple of hours.
