My friend has a 64 chevelle with maunual drums all around. He would like to convert to power drums. The current master cylinder has one brake line coming out of it and going to a distribution block. Does he need a power brake cylinder, longer push rod, proportioning valve? Or can he use the current set-up and add a vacuum diaphram? He is not converting to disks in the front, just wants to add power assisted brakes. Thanks.

He can tweak the line and add a booster.

Give him our number if you want, we have the booster and can answer his questions...866-628-8746 or 925-828-5555
