new brake line question

[SidsChopShop]

I've searched this forum and can't find an answer so i'll start a thread.

My 66 C10 SWB needs new brake lines. I want to ditch the old single port system for a dual port. I don't need power or discs I just want to have a dual port master. Would it be easier/simpler to buy a dual master and some bulk brake line and fittings or would a pre-bent line kit (for non-power drums) for a 67 be a good start? I am unsure just how difficult these lines would be to fit on the 66 chassis. Any input would be helpful

Thank you
