Thanks guys.... I think I posted in the wrong place. I  assumed the pedal assy was different but wanted to be sure. Appreciate the responses.

Oh... I kinda though so. My son is doing a 67 coupe that someone had put Granada discs on. We were have a problem getting sufficient "pedal" . That's when it struck me that was probably a difference. Didn't realize the bracket itself might be different :( Off to ebay he goes ....

Thanks again !

Which bracket is being referred to here?  If it's the pedal support I believe it's the same as for manual brake vehicles.  I did the swap from manual drum to power disc on my '67 Mustang back in the '70's and remember having to change just the pedal.  I found out the hard way.  Can't remember where I found a used one but it was shipped via Greyhound bus!  I couldn't wait to get notice that it had arrived so that I could drive to the depot in downtown SF and pick it up!

The pedal support (bracket) is different between power and non power brakes. It involves how the bracket is mounted, I believe the geometry is the same.

The 1967 and 1968s use the same "C7" parts


Let's start under the dashboard. During 1967/8 Ford used two different clutch/brake pedal supports in the Mustang. All 1968 Shelbys used the C7ZZ-6501508-B pedal support. This support is used for cars with power brakes.

Service replacement brackets are usually painted black and will have a service label on them.

A power brake pedal hangs off the top of the clutch/brake pedal support. Manual transmission cars that do not have power brakes actually use a brake pedal that is much shorter and pivots offs the clutch pedal.

My '67 was a 289 with 3spd stick shift and manual drum brakes.  I switched over to power disc brakes and remember having to change only the pedal.  The original one would not connect to the boosters push rod.  The power disc pedal was definitely a different length with a different pivot point.  My support bracket stayed the same.

That's entirely possible. You would need to put a nut under the dash to mount the power booster. The manual pedal support does not have the captured nut used to mount it.

Drum brake bracket and disc brake bracket. Drum bracket has 3 captured nuts that could be removed for use with a Disc brake set up. Most of the drum brake pedal hangers have the hole drilled for the longer disc brake pedal.
