what exactly all do i need from a rear disc civic to convert my civic, besides calipers and rotors and pads ofcourse. i have the prop valve already, do i need e-brake cables, and the whole trailing arm and brake lines or what can i use off of my drum setup that will still work?

 

I did the conversion (I have a 93 CX with rear drums stock) swapping the whole trailing arms with the e brake cables and brake lines.

I don't really know if it is possible/easy to do it without the trailing arms, e brake and brake lines.

But I guess if you live in the US it is no problem for you to find those trailing arms.
