Need help please..totally lost on from disc conversion

[crazychevyc10]

Hey guys..

Need your help again. I'm getting different information on my front disk brake conversion for my 68' and need to clarify my next step. Here's what I have done so far:

Installed rotors and calipers with 72' lowering spindles.

Now I'm stuck on the following:

Do I need to get 72' outer tie rods? Or can I use my original 68? Because I got new tie rods for a 72' and they were larger and didn't screw into housing

Also my brake lines don't bolt up to the hard line? I saw that ece website has a line conversion kit and not sure if I'm suppose to get those?

Also I don't know if I'm suppose to get a mastery cylinder or power boost and what are proportion valves?

I'm looking for the most cost effective route
Thanks guys!
