Proportioning valve question for disc brake conversion

like i said in the first post at the start of this thread im still learning. This is probably the biggest thing ive done on my dart besides replacing all old drum brake components in the rear. So my bad if i sound dumb haha.
You don't sound dumb at all, you sound smart because you're asking questions. I'm just trying to answer accurately so you will know the difference.
Well i thank you for understanding. For some reason this valve thing has been screwing with me. But i wanna sum it all up now, so i need to install the adjustable proportioning valve above the stock combination block and it needs to be attached to the rear brake line do i have that correct? Also do you think i can go to the auto parts store and just buy some pre-flared and ready to use brake lines? If not then im gonna have to go get a flaring tool and do it myself.
