I don't have an answer for your question, but my suggestion is to not convert to power brakes. Go ahead with the disc conversion and leave the booster in the box it came in. It sounds like you modified the firewall though. What does sized the firewall mean?

In order to add the booster you have to drill out a few holes to install. I already modified, so its going to happen.

Which booster?
Factory style mounting, or will fit if booster?
Pedal is important. as the wrong angle on push rod will destroy a new booster.
Did the supplier provide the information as to a stock type install, or a "Will fit if" install. YOU make it work/

Boosted brakes use a different pedal ratio, and the correct pedal pivots from a different location, (the 3/8 hole in the top corner of the pedal support).
The 68 power pedal is reproduced, and will work on a 67.
I'm struggling to understand how Willwood can't answer your questions.

I have a brand new Power pedal, Disk Brake Pad, and the mounting hardware. It is longer than the manual pedal for mounting in the upper location. PM me if you need it.

I was surprised as well that Wilwood didn't have an answer. Maybe a newer employee or something. I am going to replace the pedal, seems that is required for correct ratio.

Summit sold me the booter and said they didn't have any repro of a 67 pedal listed, only for a 68/69, he said he was a Chevy guy and didn't know the Mustang's as well.

The 68 pedal has a bend in it to clear the collapsible steering column, otherwise the geometry is the same as 67.

This should help.

Thanks, that video was very good. I now see that my Fulcrum point is off! Learning new words everyday!. Thanks much.

The 68 and latter pedals have a longer pedal pad than the 67 and earlier cars.
But as bmcgc said, functionally the same

Wilwood doesn't make or supply boosters. When I asked, they gave me the names of a couple of places that sell them.

 

[jeffr15937]

Correct, I went to Summit and bought one.
