SN95 MC and booster on a fox

While I'm ass deep into my car at the moment, I wana try to knock out my brakes while I'm there. Here is the sit-rep:
 
Booster leaks air, is rusted, and has a big ass dent in the side near teh back of the head
 
MC leaks from the fittings after a few stops
 
Now the question:
I have a SN95 MC here now, and had an offer to buy a booster for $20 from the same car as the MC. I was told it will fit but is there any bennifit/loss to doing this. I'm staying stock brakes for a while so i see nothing to loose.


 
I'm not asking about rotors, rear end, calipers.... just the master cylinder and the booster. I know all about the 5 lug swap and thats much later down teh road. The car needs to stop before I need 5 lug.
 
Any input is nice
 
Thanks;)

Thank ya much. I just have a few questions.

79-86s: Since you already have a 2 port SAE threaded MC, you can swap one from a different car. The '85 Lincoln Towncar with a 1" bore is about the best unit for most all brake upgrades. The SVO unit can be swapped in with some adapters, but is really to large to use but with only the SVO front and rear brakes
Since my car is aprox 84 mustang, this is correct right. It stated the towncar is right, not the 94+ V6 booster like I will have.

Any of the 94-95s and 94+ V6 units will work. They are all larger than the stock 87-93 V8 unit, thus will give you more assist.

So this is abut the same size as what I got?
 
According to this, I have SAE threads. Same as a stang I presume? Just run new line to the prop. valve and flare on a Metric fitting and call the MC good?

Sorry for the extra questions, I just wana be 100% sure of what I'm getting into before I start.
 
As of now this project is a go as soon as I make a few calls and get me the booster.
 
Edit:
Now witha few random pics that show my current booster and MC. In one picture you can clearly see it has rust on it, and I'm not sure if you can see but all around where the MC attaches to the booster, it's wet. I assume it to be brake fluid. Hence one of the reasons I wana change to a better and working setup
 


P.S. these pics were taken on 2 different days

The way I read it (and I'm studying for my '86 5 lug swap) the 85 Town car is the most desirable one to use mainly because it bolts right in to the 86 down lines and has a nice size bore. The SVO will also work but may be overkill for an otherwise stock system. 

You'll need to use SAE to metric adapters for the lines to use the SN95 stuff but it should be a bolt in other than that.

I'll see/make sure Napa has SAE - metric adapters then we'll rock this. Thanks for the help guys. Any other comments still welcome though

first i wanna know how a car that doesnt drive can leak from the MC after a "few stops."

second, i want to know what the stock bore size is on your MC and the bore size on the unit you have pictured

third, what effect will the size difference(if any) have on your brake system/pedal feel?

fourth, is the sn95 booster a direct bolt-in?

fifth, how will the sn95 booster affect the system and pedal feel?

all this information is in the link 32V posted. when you have those answers, you will already know if it will work for you or not.

dont guess, dont base your information on what you "hear" works. research, and decide. if you ever get to actually drive your car, brakes are not a system to be playin around with or mods to it taken lightly.

1. It does drive, just not too far. I'm talking even just sitting with the motor running. Hit the brakes a few times, it will start to get moist all around all the connections
 
2. I'll find out for you shortly
 
3. More then likely not much. It's not as much for feel as I have the parts to do it avalable to me, and whats on the car isn't good anymore
 
4. You need to elongate the bottom hole about 1" from what I understand. Other wise yes. Then just some SAE-metric adapters or running some new line to the prop block and it's done
 
5. Again, I'm not sure. One of the reasons I posted to ask
 
I'm not guessing. I'm asking serious questions.
 
The car can hace 389593473984238946 HP and go 300 MPH but without brakes your screwed. I'm already ass deep into the motor and the things I need to change/fix are right there, parts are avalable, my stuff doesn't work..... why not just fix it while I'm there?

I think the point Gumby was trying to make is all the information to your "not sures" is in that link.
