Default Re: Dual chamber master cylinder for drum brakes

I remember a '69 Dodge A-100 van and a '72 Ford pickup I had both had dual chamber MC, drum brakes all around, and no power booster. Wondering if one of those might work, or something for a mid-size Ford car of that vintage? I can do the brake line plumbing to separate front and rear brakes. I know Rambler was the first to have that feature in the early '60s.
The one we have used over the years in the HAMB 1952-59 Ford Group is the Autozone M1485 this is a rebuild unit,so why a rebuilt you ask ? A lot of these are USA made Bendix or Raybestos castings which are better than the offshore new ones made in India or China if they have a few in stock look for the Bendix on the underside. This is listed for 1967-68 Mustangs with drum brakes. Here is a NOS one so you can compare. https://www.ebay.com/itm/NOS-67-70-F...-/402045990606 WARNING ! Do Not use the pushrod that comes with some of these, you should use your stock 1952-56 push rod. The push rod that comes with some of these has a clip that will lock it in place,removing one is pure Hell you can also toss that clip off the end too.
