i missed the booster bracket , but I made friends with the guy , so going back this Saturday for the booster bracket .
I am starting to clean stuff this Saturday also , everything has a 3/4 " of caked on mudd from sitting in the desert . If I had a choice I would have passed on this stuff , but this was my only option and cheap , I am replacing bearings,rotors,calipers,booster ,king pins,bushings with new/rebuilt stuff . so no biggie

Damn, I'm good. I figured out what the rear end tag was before you posted a photo of it. I should have been a detective. LOL 
Is the booster the bell crank (cantilever) type? I can't see it clearly in the photo. The booster input rod looks short is why I ask. Depending on what bell crank version the booster is (IF that's what it is), it MAY cause some difficulties with the flat input bar lining up with your brake pedal. --there's a longer version and a shorter version of that booster's input rod to the brake pedal.

Yep, bell crank style booster.
The photo of the warranty plate you posted said 1978. Somewhere around '77/'78, Ford made a change to that style booster where the flat input rod between the brake pedal and the bell crank mechanism was longer than previous years.
HIO has that style booster on his truck. I believe I remember him saying his booster came out of a '75 and that his booster connected directly to his brake pedal.
I also have that style booster I pulled from a (I believe) '78/'79 F150 --although I didn't use it. I went with a dual diaphragm booster from a '75 F350 instead.
It MAY be that you'll need the pedal hanger from the donor truck to mount that booster in your truck.
The donor truck should have had a cast iron Kelsey-Hayes disc/drum brake valve on it. Did you get it or, what do you plan to do for the brake valve?

A brand new (not rebuilt) MC, is around $50.00 bucks. Not worth the hassle of a rebuilt unit and especially not worth getting a used MC of unknown condition that's likely rusty inside, will pollute your brake system with rust scale and debris and have a high probability of failure, soon after installation.
I learned my lesson on using rebuilt/used MCs a long time ago. (you can learn a lot from a dummy --as the advertisement slogan used to say).
Edit: A brand new conventional 1.00" bore cast iron MC for that year model/series donor truck is $35.00 bucks

Core charges are only applied if you are buying a rebuilt MC. There won't be a core charge on a new MC.

In addition to Steve's correct info I can tell you WDM-BV4 took axles part number D6TZ4234C. These were for 1/2" brake backing plate bolts. Ford had some 9"ers with 3/8" brake backing plate bolts back then. Same bolts that hold the axle's retainer plate. I can't tell if it's got ball type or tapered type axle bearings. In 73/79 Ford showed both possibilities. Not bearing per tag.

Does your information give the axle # rating? If it's ~3300#, the bearings will likely be the ball bearing type. If an axle has a rating of 3600# or greater, it would have cylindrical roller bearings.
--on the 3/8" backing plate bolts, does your information give the (4) bolt hole flange pattern dimensions on the end of the axle tube? --in other words, does it specify if it's the later model 'Torino' style large bearing axle housing ends when it lists the 3/8" backing plate bolts?
Reason I ask, a guy from the Dentside forum put an '84 Bronco 9-inch rear end under his Dentside. The '84 Bronco 9-inch rear had the newer 'Torino' style large bearing ends on the housing tubes.This means the '95-'01 Explorer rear disc brake assemblies will directly bolt up to that 9-inch housing flange --with a change of axles.

Being that they are 28-spline, I suspect the axles have ball bearings.

78/79...single speed non-locking...2.75 (3.75M). Our tag number here is covered by parts list 91. Looking up a rear axle housing for our tag it shows:
D4TZ4010E...Use with WDM- w/ball bearing or Timken tapered roller bearing...73/78.
Looking up the axle retainer plates it shows:
D4AZ4020B...use with (a bunch more also) WDM-BV4....1/2" brake backing plate bolts...1975/78. No other info listed.
So I looked up the 1001 gasket for this retainer plate. Only listed the I.D. then I switched to my 73/79 Car slide to look at your "Torino" style retainer plate. BTW, the Car slide only shows the I.D. of the gaskets. I'll try the 65/72 slide in a second. So the 73/79 Car slide shows two Torino plates.
74/79 B (Torino then LTD II)..D4OZ4020B...use with tapered roller axle bearings.
73/79 B " " " .......................D3OZ4020A...use with large wheel bearing. Which took a D3OZ1001A gasket. Which has a 3 3/16" I.D.
The 65/72 Car slide was no help. So I went to 1984ish Bronco. The D3OZ4020A fit WDM-CF,CL,DB,DD and DB1 in 1980/81. But still no dimensions listed. Sorry buddy.
