68 B body master cly question

Is it a different master for power brakes.? Car is drum all around. Got a new, not reman master from Rabestos and it says for both manuel or power. Just checking to see if power master is different then manuel.

Doug...'68 parts book says p.n. 2808599 fits all drum brake vehicles power and manual.

Thanks. Just wanted to make sure before i put this one in.

your should look diferent than this one off my power disc 68

67-70 power or manual drum uses the same master cylinder.

Actually that is what it looks like. paper work said power or manuel drum. It's a new master from Rabestos. But does have lines on the other side towards the inner fender.

power or manual, makes no difference

drum brakes only
