1966 dual master cylinder

about 3 years ago I got this info from grumpascreature and I have been looking in this Brakes forum all the way back to the 4th page.
I seen a new member buzzkill71 hit a wall because he has the single pod master cylinder, even though my brakes do a great job in my little Valiant Sedan and all new I see it is time to move forward and get a dual MC.
I looked at many!!!MANY threads and still could not find what MC to get and Portioning Valve and push rod for a 1966 Valiant.
It sure would be cool to use my existing brake lines :glasses7:
Grumpascreature said Quot= The master cylinder you are looking for is A1 Cardone part number 10-1523 ... :help:
Looking for any help at all on this and maybe we can complete a thread on this upgrade for this early A 66 Valiant.
I do not want front disc bakes at this time and looking for the safety factor.
The part #in this thread I have no idea where or who to call or find it.
where is a list of parts that will bolt on this 66 plymouth A body ?

Thank you for all the help and time it will take to get this dun ASAP :coffee2:
After seeing our members Barracuda I think it's time to park Victoria till this is dun.. :clock:
