What does it cost in total to put power brakes on my Mustang?

The instructions and plans with a new pin costs $15.00   A piece of steel to make the bracket costs about $5.00   A used booster costs $40.00 at salvage yards   You build it - the labor is free, and you can have power brakes for $60.00   OR have me modify your parts for $120.00 and it will cost you $160.00 TOTAL if you get a used booster.  I recommend a rebuilt booster rather than taking a chance on a used one, unless you know the condition of the used one.

Will it fit my 4 wheel disc brakes?
The kit fits ANY TYPE or combination of drum or disc brakes,  The instructions specify what master cylinder to use.

What about Falcon and Ranchero?

Yes, with a bit of extra work it can be made to fit other applications, although not quite as easily as the 65-66.
60-63 Falcon must use original style master cylinder due to shock towers.
67-70 Mustang / Cougar - use the 67-70 Mustang/Cougar booster and pedal now offered by MustangSteve.

Will the tandem master cylinder clear the shock tower?   What about clearing an export brace?
Yes, it clears the tower by about 2 inches, and is not even close to the export brace.  (except on early Falcons and Comets, where the single piston master fits easily, but the dual piston requires a dent in the shock tower.)

Will it fit a 351W with Heddman headers?
Yes, it clears with no problems whatsoever.

Why will it not fit my car with original manual transmission?
The clutch actuation rod comes through the firewall in the exact spot where one of the booster studs must attach.  If you are using a T5 or Tremec tranny with a MustangSteve cable actuated clutch, it will work fine.   Click HERE for a superb retrofit cable clutch setu
This conversion fits 1965-66 Mustangs with automatic transmissions
(will fit standard if you have cable or hydraulic clutch only) 
with one kit to fit 67-70 Mustangs & Cougars

Factory Fit and AppearanceFits better than the original 65-66 booster and works better, too.

MustangSteve Booster Shown with 65-66 Mustang Manual Transmission Pedals, Cable Clutch Conversion, optional 70 Mustang 1" Disc Brake Master Cylinder
The power brake conversion bracket (65-66 Only) is a 10 ga. steel bracket that is welded to the front of the pedal support bracket (under the dash).  It provides the support and correct bolt pattern for the power booster.  The pedal support assembly then bolts back in to its original location, with 2 additional holes required in the firewall plus enlargement of the original center hole where the master cylinder fits.  It provides a very nice, neat, factory looking booster installation that can mount a dual piston master cylinder (The detailed instructions specify the correct one) or you can use the original Mustang master cylinder
The pedal pin (65-66 Only) where the original master cylinder hooked up to the brake pedal must be replaced with a new design pin in a new location on the pedal and welded into the pedal arm.  This weld must be done by a competent welder!  The new design pin, having a flange added on the pin side of the pedal, allows the new pin to be welded from both sides of the pedal arm, which makes it virtually indestructible, and stronger than the original Ford part.

The original pedal-mounted brake light switch is utilized.  Pedal height is slightly lowered, like a factory power brake car would have.  (Remember, it takes less travel to actuate the power brakes due to the revised pedal ratio, and the lower pedal makes for a more comfortable driving position).  Two metal brake lines must be fabricated to reach from the master cylinder to the proportioning valve or to tie into the existing lines
