Disc brake conversion pics and questions

[Lugnutz65]

Yes, I did review the relevant FAQ section about disc brake swaps but didn't find my answer.

So thanks in advance for the help.

I have 3 questions.
1. Do I run the 3/16" line from the MC and prop valve to the front discs?
2. Do I run the 1/4" line to the rear axle flex hose?
3. Do I keep the rear axle 3/16" hard lines that come off the rear axle distribution block?

The back story:
I'm installing a CPP front disc brake kit in my 1965 C10. The CPP tech help line was not helpful.
The CPP supplied front brake hoses that came with the kit have fittings for a 3/16" line. I will be using a 1995 Chevy Blazer Booster and MC.

My current 1965 front drum brake lines are originally 1/4". Then the 1/4" line runs back to the splitting block at the back axle. The hard lines to the rear drums are 3/16". That's the original stock setup.
