C20 to C10 conversion question, wanting confirmation

[R.O.B.]

I have a 67 C20, and I just bought 70 lower control arms. I will be converting from drum to disc in the process, and converting from manual to power brakes as well. The way I understand is this:

Use a standard or dropped spindle from a 73-87 C10 w/1.25" rotor
Use upper and lower ball joints from 73-87 C10
Use brake hose for 73-87 C10
Use an outer tie rod as an inner tie rod from my 67 C20.
Use an outer tie rod as an outer for a 73-87 C10
Use POL HPAS6570 tie rod adapter to mate the two different tie rods.

So do I understand this correctly? Or is there a tie rod combo that doesn't need the special POL adapter?

And what about the hard brake lines? Are they the same size, or do I need to buy new ones?
