those that have changed to cobra rotors/13"rotors----- QUESTIONS

[Pur Pony]

I have read a little about doing the 13" cobra brake swap.

My question is.... can I use my existing master cylinder from my 84 SVO??? Brake lines??

and if not do I need the full brake lines off a new car? and how and where do I tie a proporsioning valve in?

are there any drawings around the net on this?
