64-1/2 & early 65 had this type of
pedal pin.
(Brake light switch was on master
cylinder instead of pedal pin)

Unique to 68 Manual Brakes.
Bracket appears to have been
designed to hold a switch, but
was never utilized for that
purpose.  Acts as a positive stop
for the pedal's upward travel.
67 Power brake pedal.
Note the notch in the pedal about
1/2 way between the pivot and the
pin.  That notch gives extra
clearance around the clutch pedal
shaft when used on manual
transmission cars.
Power brake pedals measured 5.0 "
from center of pivot to center of
pedal pin 1967 - 1969
Manual brake pedals
measured 2.0" from center of
pivot to center of pedal pin for
all years 65-70.
Power brake pedals measured
4.5 " from center of pivot to center
of pedal pin 1970 only
Power brake pedal 1970 only.
Note the steeper curve right
below the pedal pin to clear the
wider collapsible steering
column.
All 68-70 pedals have that offset.
All pedal assemblies had 4 of these plastic bushings.
Two go in the brake pedal pivot.
Two go into the pot metal bushings in the pedal support.
They seldom wear out on automatic cars, but almost
always wear out on manual cars.
WHAT FITS WHAT...

Brake pedals are identical between manual transmission and automatic transmission, except the foot pad
part.
A pedal from an automatic car can have the foot pad trimmed to fit on a manual transmission car of the same
year.

65-66 brake pedals are same for manual or power brake cars.

67 manual brake pedal will fit in 65-66 as exact replacement.  65-66 pedals will fit the 67 car.

68-70 manual brake pedal will fit 65-70 and work fine but has more side offset.  Foot pad winds up in exactly
the same spot, though. The foot pad is wider on the 68-70.

65-67 manual brake pedals will NOT fit in 68-70 car due to the wider steering column. (fits but not well)

67 power brake pedal will only fit 67 car.

68-69 power brake pedal can be utilized in 67-70 car as long as the 67-69 booster is utilized.

70 power brake pedal can be used in 67-70 car as long as the 70 booster is utilized.

70 booster cannot be used on 67-69 power brake pedal

67-69 booster cannot be used on 70 power brake pedal.

IMPORTANT:
 On cars with manual brakes, the steel lever arm you see welded to the top of the pedal serves as a stop to
keep the pedal from being able to travel back towards the driver far enough to pull the pushrod out of the
master cylinder.  If the rod comes out of the master cylinder, there will be no brakes.
 Most master cylinders for manual brake cars have a positive rod retention clip built into the piston.  The rod
snaps in place and is very difficult to get out. MOST DISC BRAKE MASTER CYLINDERS DO NOT HAVE THAT
FEATURE, since they were mostly designed for use with a power booster.
 When swapping master cylinders and brake parts, BE SURE there is no way the rod can be pulled out of the
master cylinder, by either a positive lever stop on top of the pedal, or by positive rod retention clip in the
master cylinder, or both.

 74 Maverick non-power disc/drum master cylinder with 15/16" bore is very popular and has the clip
 67-70 Mustang power disc/drum master cylinder with 1.0" bore does not have the clip.
Boosters for 67-69 had curved input shaft
Boosters for 1970 had straight input shaft
65-66 pedal support
64-1/2 Pedal support is identical except the square hole on
the driver side, (denoted by a red square in the picture)
where the clutch pedal stop bolts on, is a 1" long vertical
slot so the clutch pedal height can be adjusted.  That is an
easy mod to add to a 65-66 by simply slotting the hole.
64-1/2 -66
pedal support
67-68 pedal support
The 67 - 68 power brake pedal pivots from a 3/8" diameter
bolt that goes through two holes up high in the support.
The holes locations are shown by two yellow markers in the
picture.
Early 67 pedal supports did not have the 3/8" holes.  If
adding the power brake pedal, the support must be drilled.
Hole location is critical for the pedal to fit properly.
The 69 power brake pedal pivots from a 3/8" diameter bolt
that goes through two holes up high in the support.
The hole locations are shown by a yellow marker in the
picture.
The manual brake pedal pivots from the pot metal
bushings.
69 Mustang and Cougar
pedal support
70 Mustang and Cougar
pedal support
The 70 power brake pedal pivots from a 3/8" diameter bolt
that goes through two holes up high in the support.
The hole locations are shown by a yellow marker in the
picture.
The manual brake pedal pivots from the pot metal
bushings.
Typical installation of brake pedal and stop light switch.
67-69 Midland (clamp type) power brake booster
Note curved end on the input shaft on the left.
67-69 Bendix (crimped type) power brake booster
Note curved end on the input shaft on the left.
This booster requires a spacer between the
booster and firewall.
67-69 Midland (clamp type) power brake booster
Note spacer on front of booster where master
cylinder bolts on.
67-69 Bendix (crimped type) power brake booster
Note curved end on the input shaft on the left.
This booster requires a spacer between the
booster and firewall.  Spacer is shown clearly in
this picture.
1970 Bendix booster is identical to the 67-69
Bendix booster with the exception of the input rod
being straight instead of curved.
This template is used to modify the firewall when
converting from manual brakes to factory type
power brake booster on 67-70 Mustangs and
Cougars.
Most important thing is the big hole for the
booster must be raised up from the original
master cylinder hole position.
