Hey guys
I need a couple measurements and a pic.
The pic I need is of how the brake pedal assembly attaches to the frame.
The measurements are of the position of the whole where it goes through the firewall.
If someone could measure up from the floor and over from the kick panel I would be very grateful.

Is this for a 55-59? If so I'll try to get pics and measurement tomorrow.

On my 57 the brake pedal is about 19 inches over from the kick panel and 6 inches up from the bend where the floor meets the toe board. Sorry couldn't get under it to take a pic of the master.

The master fastens with 2 bolts that thread into a plate that extends out about a couple inches from the inside of the frame. That's the best I can explain it from memory...

On my last truck I bought an adapter that lets you bolt on a newer dual master without a power booster and still uses the original pedal. Worked great, I'll try to find out where it came from.

This is the part if you're interested, from ECI

I'll try some pics old and new:

Hope these help. I didn't get the measurement 'cause others beat me to it.

OrrieG · 04-09-2009, 08:41 PM

What are you after? The factory manual shows the bracket and the factory holes and rivets but no dimensions, just reference to the factory holes. If it will help I can scan it for you. Are you wanting to figure out how to add a newer mc and booster?

Kim57 · 04-10-2009, 12:24 AM

Thanks for all the replies guys.
The measurement on the hole in the firewall was my main concern.
I got a new brake pedal assembly which is slightly different than stock.
It bolts to the stock location on the frame.
When I replaced my firewall I neglected to get the position of the hole for the brake pedal. I just wanted to be sure I drilled the hole in my firewall in the correct spot.
