Greetings,
Anyone know of a under the floor hydraulic master cylinder setup for a 54 F100?

 

Not sure what you're asking. You already have a single reservoir hydraulic master under the floor. R U looking for a dual master, power master, power dual master, hydraulic power master cylinder?

Just re-read your post. Are you asking about a hydraulic CLUTCH? I may have mis understood your post.

 

I already have upgraded to a power brake booster with double master cylinder under the floor. The transmission is the original 3-speed manual.
We are going to upgrade the power train to a V8 with a modern manual transmission. As such the linkage for the clutch most likely will not work. Thus to use a modern 5-6 speed will need a hydraulic clutch setup. As the truck is still using the original pedals, I would like to keep them. So this now means fabricating a clutch master cylinder mounting that is also under the floor.
We will also add remote fluid reservoirs as well.

 

Gotcha!
Here's some reading for ya:

Here is how I did mine on a 52, should work the same on a 53-56. Retained the original pedals.




Bellcrank to change the clutch motion from pull to push.





Clutch master installed behind the brake master.
