I have a 1950 Flathead V8 that I inherited and it runs great. One of the first things I wanted to do was to change all of the fluids in the truck. I cannot locate the master cylinder in order to change the brake fluid. Can anyone help me correct my ways? I know this a stupid question but I want to do it right!

Yeah, that's a real convenient place to have it. You just have to make sure nothing falls into it while your under the truck loosening the cap, while you're fillng it and then again when your back under tightening it up.
Oh, yeah, one more thing, you might want to have a tray under it for when the fluid over flows out of it.
Look at the bright side; at least when it overflows, it isn't dripping on anything but concrete. You don't have to sweat drips from the bottle falling onto the fender paint. A funnel is a big help. When you bleed it, you also don't have to worry about "burps" spraying brake fluid on everything.
They could have made the access hole bigger and located it directly over the cap. I have to use a funnel or I end up with brakefluid all over the floor.
The only idea that I think would be more dim witted is mounting the battery under the floor board so the vapors from the battery could eat the floor from the bottom up and the mounting bracket would rot through the bottom, now that would be really stupid. But I would think that after they had the brake cylinder under the floor boards no one would come up with such a stupid idea, right?
I can see mounting the master cylinder where they did, becuase that where's the brake pedals were mounted, I agree they could have either inlarged the hole or knotched the frame, but why would they mount the battery under the floor in later models?
Bob, you can be absolutely sure that it somehow saved Ford money. That was their motivation for everything. I'd guess the underfloor mount is a pound or so less metal, sheet metal vs. the heavier steel for the BonusBuilt mounts, and maybe has a shorter cable run. There is no other reason I can think of.
