Issues getting correct brake lines for LMC power disc brake booster

So I have a 68 I am converting to a disc front. I've bought it all from LMC cause they are local to me. But the technical help is atrocious. I can't get any answers from them. I'm assuming the booster is a CPP but unsure as the box it cam on is unbranded. I purchased their disc brake conversion lines which are inline tubes and nothing is lining up. And 1 brake line doesn't fit the proportioning valve. Has anyone ever used the lmc power booster and what lines did you use? I was under the impression from them it should work but I'm lost! Do I need a different prop valve?

When those brake lines are shipped they do not exactly conform to to where they install. They bend them to fit in the box and you will have to make adjustments as necessary. Personally, I bend my own lines from tubing I get from NAPA

Yeah I figured ill have to do a little bending. However one of the lines is to big for the prop valve. So I'm wondering if I have the right lines or need a new proportioning valve

I had to install fitting adapters when I installed my CPP proportioning valve with the stock '68 lines. I got the adapters at Napa.
