Disk Brake Conversion Question

I am almost ready to finish up my Dana 44 build, but I have an e-brake question regarding the rotors I want to run with my rear disk conversion. I will be running Ford Exploder rear disk brakes but I would like to use ZJ rotors. The rotors fit up fine with Ford caliper and recenter the rotor in relation to the caliper. I want run e-brakes but I have not been able to find anyone that can tell me if the ZJ rotors will fit on Ford e-brakes i.e. same ebrake drum diameter.

Can't say for sure, but I thought I saw somewhere that they are the same brakes. On Rock Auto's site, the parts cross reference to each other.

Why not just use the exploder rotors?
