Aside from the fixed nuts on the manual brake support are there any physical differences when compared to the power brake version?
Thanks

I do not think so, I have removed the nuts and added the power brake booster.

Thanks for confirming you have successfully made this conversion.

Shawn : Back in the mid-eighties, I decided that I wanted to add Power Brakes to my 67, and started picking up parts to do so. One thing, that was still available from Ford at the time, was the Power Brake Pedal Support, C7ZZ-651508-D (pictures attached). Several years ago, after beginning disassembly of my 67 for Restoration, "I got more serious" about doing so, and have accumulated a lot of information about how to make the conversion. One of the interesting things I found out, was that, apparently, on the early 67's, the 3/8" upper holes for the pedal assembly may not be present in the Manual Brake Pedal Support. However, if not, there should be knockouts for the holes for the bolt.
I found a couple of things which may be of interest ; first, an article by Master Power Brakes. Disregard the "Parts List shown, as it is based on their Replacement Parts, including metric nuts. I am attaching this mainly to show the Pedal Support. Instead, follow directions that came with the Ford Conversion Kit (copy attached which I received from our own 67gtasanjose a few years ago - thank you again Richard).
Shawn, you didn't note if you were just replacing an existing Pedal Support on a car with Power Brakes, or converting Manual Drum Brakes to Power Drum Brakes. If you are converting, there are a few major things to be aware of ; you will need to elongate the hole in the firewall for the Power Brake Booster and Brake Rod ; you will need a new Master Cylinder (Power Drum Brake and Power Disc Brake Master Cylinders are not the same ; the 1967 Power Brake Pedal for Automatic Trans mission cars is unique to 1967 (also, a non-Power Brake Pedal cannot be used.
If you need more info in regard to conversion, feel free to PM me.
Hope this helps,
Bob

Hi Bob,
Thank you for taking the time in preparing the response. I am converting a non power drum car to power disc. I have everything from another 67 parts car with the exception of the pedal support. Thanks for pointing out the firewall hole needs to elongated. I have another 67 car with power disc I'll use for reference.
Kind Regards,
Shawn

Shawn : For the firewall modification, I am attaching a blow-up from the Instruction sheet that I attached previously, as well as a separate sheet that was included with a similar Kit from 1968. The cut-outs are identical. These may be of better help than tr6ying to copy from another car.

Yes, the power brake version has a nut at the outer / upper corner for the brake booster to attach to. It's possible to weld a nut to the manual brakes version to simulate this. The missing firewall holes described above can be marked using the brake booster as a template source.
