SSBC proportioning valve questions

they are pretty damn hard to double flare. I think I am going to bend and cut all mine first and then take them to a brake shop that has a hydraulic double flare tool. I'll pay them to flare the stainless lines, unless I can find a tool that will do it that is not too expensive.

The cheap tools will not touch stainless. I tried. A buddy has a snap-on tool, so maybe I'll try it first.

Anywhere past the distribution block is fine. Most put it on the frame rail away from headers.
