Im having a heck of a time finding a replacement master cylinder for my 72 barracuda. It has 4 wheel 10 inch drums and manual brakes. For some reason no parts stores can get a replacement, and I was wondering if there is another application I could use to get by with for now. I'm not ready to drop a grand switching to disc and am just trying to freshen these up to get the car on the road.

Rock Auto lists it.
Same master cylinder was used on B bodies, ask the parts stores if they list anything for a '72 Charger manual drum.
