On my 1966, I converted to a manual dual port system. I rebuilt the drums and used a new master cylinder for a 1967 truck, no prop valve; and bought a new stainless line kit from Inline Tube (P/N CTB6607) , to my knowledge this is still the only manufacturer of a 64-66 dual line conversion kit.

I have used this current setup as a daily driver and weekend hotrod 9 months out of the year since 2014 and have had no problems. Hope this will help aid your decision, good luck!
