Steve, the parts you used seem to be new. What are the exact part numbers and where to buy these? would it work with a 1977 F150, disc front and drum at rear?
The booster seems new too.
I'm currently at work but, when I get home this evening, I'll give you the part numbers/sources for the components I used.
The booster is a dual diaphragm (long input rod design) for a '75 F350. I traded my wrecking yard core booster in on a newly rebuilt booster. It can be purchased through NAPA, O'Reilly's and from various other parts places locally or online. The part number is 54-73112. --this booster is for a non-bellcrank bracket assembly.
Great information you provided, thank you. After doing some limited research on this subject, I'd like to ask you.
I see that on my 77 F-150 Master Cylinder (MC) the Bore Size indicates 1 inch and a 1992 Ford Explorer's MC is also 1 inch. The Bore Size on for my 1993 F-150 is 1 1/8 inch, will the 1 1/8 inch bore size MC work on my 77 F-150?
Reason I'm asking, because I got an extra MC in the shed for my 1993 F-150.
Lastly, the two wire pigtail for the new modern plastic MC, where do they get hooked up to in my 77 F-150? Thanks for your time W/my questions.

I don't know what booster you have (bellcrank style or non-bellcrank style) but, with a 1.00" bore MC, I'll assume you have a single diaphragm brake booster --possibly the 11" bellcrank style(?).
Going from a 1.00" diameter bore to a 1-1/8" bore will be a big jump. Going up in MC bore diameter will mean an increase in the force it takes on the brake pedal to get the same amount of braking action from the 1.00" bore MC.
Smaller MC bores will produce more output pressure than a larger MC bore, for a given amount of force applied to the brake pedal. A smaller bore MC will have a longer pedal travel. A larger bore MC will have less forward travel of the brake pedal.
Once you progressively go above a 1.00" bore MC, it becomes increasingly more difficult to comfortably apply enough force on the brake pedal to get the vehicle to come to a stop within a reasonable distance.
It's also more difficult to apply sufficient force on the brake pedal, with a MC that has a bore larger than 1.00" that's mounted to a single diaphragm booster.
The '93 F150 MC will have ports that exit on the right side of the MC body (if that matters to you). The other thing with it is the primary port is an M18 x 1.50 metric size. This is intended to screw a separate proportioning valve into this port that's designed to plumb to an ABS unit --something your Dentside wouldn't have. The add-on '93 F150 factory proportioning valve that goes into this port is about $50.00 dollars or higher (about the cost or more of the MC itself).
I didn't hook up the float level on my MC because it's a simple matter when you're under the hood to just glance over at the MC and you can see how much brake fluid is in it, without having to take the cap off. If you wanted to tie the float into the brake warning light, I'm sure there's probably a wiring diagram showing the pin-out to be able to wire the float in parallel to the existing pressure differential valve switch.
Steve,
You made complete sense, thanks for clarifying. When I get to this project (hopefully within the next month), I'll use a 92 Explorer's MC. Though do have a lingering question, are the 92 Explorer's MC thread size metric? Or will my 77 F-150 brake lines thread into the 92 Explorer's MC?

The '92 1.00" bore Explorer MC will have the same M10 x 1.0 and M12 x 1.0 metric bubble flare fittings as on the 1-1/16" bore '95 Explorer MC I have.
Line fitting adapters don't make for professional looking installations. You can get the ISO metric bubble flare direct-connection fittings from Classic Tube.
The M10 x 1.0 fitting is part number ST8036.
The M12 x 1.0 fitting is part number ST8040.
You'll need to fabricate at least two lines between the MC and the existing disc/drum brake valve.
The only main feature about the pre-'95 Explorer/Ranger MC I'm not crazy about is its downward-sloping reservoir. It doesn't keep the MC from working but, it messes with my sense of symmetry and things being balanced and level looking.
If you don't like the sloping reservoir, there is a service replacement (that's shaped much like the reservoir on my MC) for a 1999 Ranger MC that's more level and could be swapped onto the '92 Explorer MC body.
....there's also the option to run a '99-'04 SN95 V6 Mustang MC. It will have a 1.00" bore and a level reservoir. The only main difference is the ports on it exit off to the right side. ('94-'98 SN95 V6 Mustang MCs had a 1-1/16" bore with right hand ports and a level reservoir).
ultraranger,
After reading more of what you provided last June 23, 2016, I'm confident now I got the source and part numbers information needed to perform the modern master cylinder conversation on my 77 F-150. Although I'm not familiar W/bubble flares, so I'll Google the subject and determine if my double flaring tool is capable of making them, or if I'll need to buy something additional to perform bubble flares.
At any rate, the information you provided is unquestionably first rate. Thank you again.
