I'm trying to determine which master cyl to get.I will have 4 drum brakes in my 53.Is there a difference between a 4 disc and a 4 drum master cyl.I'd like to go to my local Napa dealer and know what to ask for.I was thinking of getting a 73-77 4 wheel drum brake master cyl/booster.Is that what I should be asking for?Does it need a flow control or any thing else?
Thankyou, Lothar
