77-79 Brake Pedal Hanger

Here is a link to a forum member over on Ranchero.US who installed a '78 Lincoln Mark V brake pedal bracket for a hydroboost conversion, maybe it will have the info you are looking for. Look at post #37 for the bracket and pedal pivot change.

I read through that and I am not sure I completely understand.

I get the pedal travel angle was wrong, hence needed a new setup. He procured the interior brace section, but then began talking about new holes and/or new pedals.

Did he use the interior brace AND pedal assembly from a 78 Mark V? Did he have to modify the brace or the pedal assembly, or both?

That is where I get lost. I'm good with the buying new parts to make it simple, and I am good with getting the brace out of a Mark V if needed.

I think the thread was a little more complicated than it needed to be (for the casual person interested only in Hydroboost) as there was all the engine swap stuff in there. Not to say he wasn't doing incredible things, it is just that he would be going back and forth...

Here is some more information I found on the topic. Granted, geared for late 60's Mustangs, but same line of thought goes into the matter.

Seems there is not a direct bolt in, however the Mark V setup, with pedal modifications (of which I am not entirely sure), may be the easiest and most direct method.
