Question, what foot pedals are you using, Wilwood or mustang? Because I have a Wilwood pedalbox, I had to make my own brake pedal, post 194. Whitby also sells one.

I have a sn95 pedal box, with '93 brake booster (whitby) and a '95 Mercury Villager MC (abs or non abs - your choice) that needed to have a bit of machining (similar to what whitby does). I enlarged the mount holes on the MC to 7/16" and increased the depth of the MC plunger to 1.00" from 0.875 with a 7/16" bit. If you go with the abs MC, you'll need to do a little bit of adaption to get to the inverted flare brake lines of your car. I used 2 spacers inbetween the MC and the booster.
You'll also need to move the steering flange bearing to the inside of the Footbox,

trim the the 3/4" frame tube so that the booster will have room to fit,

and will also need to enlarge the hole where the booster will enter the footbox. To mate the booster up to the footbox wall, you'll need a spacer in between the booster and the front wall. ReplicaParts.com does a spacer that fits and seals the gap well.
And finally, if you have a sn95 pedal box, you may need to do a little knotching on the pedal box to get everything to fit (because you moved the flange bearing to the inside of the box).

Hope this Helps!

Whitby also includes the reservoirs, bracket, hose and nipples that fit in the MC.

I already had the MC and remote reservoirs for my manual setup so didn't need the full Whitby setup. I bought a 93 booster (https://www.summitracing.com/parts/aaz-54-73207) and already had a 95 Cobra MC from Breeze. Everything bolted right together, didn't need to machine anything (except for cut a 2.5" hole in the firewall with a hole saw - use a wood template bolted on) and also created 3/8'' spacer between the booster and firewall. For the gap in the frame, I cut the frame at about 1" and 7" and bolted an 8" long piece of square tube on the outside (credit goes to Mike Everson's threads for that idea).
As a caveat, I have yet to drive it so can't attest to how well it all works. I have GT brakes all around so all the parts should match.

For you guys retrofitting from manual to power be aware that if you modified the pivot of your pedal (as you should have if you used a donor pedal box from a car originally equipped with power) you will need to go back to the original configuration. If you use the manual pivot geometry with a power booster your brakes will be ultra sensitive and act kind of like an on/off switch!

Got a manual? It'll be in the donor parts prep section.

Yes i did cut down my brake pedal and am in the process of trying to find a replacement. But thanks for the reminder Jeff.
Anybody needing one already cut down i will trade you and pay shipping, will need to be for 1987 to 1993 mustang with manual tranny!

I checked out my car yesterday, looking for the brake pedal mod described in the Mk3 build manual and mentioned in Jeff's post. Here's what I found:
1.) The pivot arm has been moved to the lower set of holes referred to in the build manual.
brake pedal pivot mod 1.jpg
2.) I see no sign that the pedal arm was modified by removing 1.5" between the pivot and the pushrod attachment point, as the build manual instructs.
brake pedal pushrod modified.jpg
3.) What I did find was what appears to be a "custom" pushrod extension, that was welded to the master cylinder pushrod. The extension looks like the letter "P" laying on it's side with the loop pointing down towards the floor. Like this crude drawing:
custom pushrod diagram.jpg
brake pedal pushrod _ top side.jpg
brake pedal pushrod _ underside.jpg
Does this look like it would work for the proper leverage on a manual braking system....?? Or, should I scrap the "custom" pushrod and...
A.) Follow the build manual instructions about cutting and sectioning the pedal, then replace the m/c pushrod?
OR
B.) Switch to aftermarket pedals (i.e. Wilwood or Maximum Motorsports Pedals)? Is there a Forum Sponsor that makes/sells such parts?

Craig ,If the brake pedal pad is at the same height from the floor it has been cut down, im out of town for a couple of days, when i get back i will measure the length to compare to yours.
Thanks
Walt
That should be same as the clutch!

Craig,
What you have there is an adjustable pushrod. It allows you to change it's length to adjust the pedal height but does not change the geometry of the pedal.
Jeff
That pedal has bee modified. In fact it was done by me. I don't cut and reweld the pedal. I cut off the pivot on the top and drill a new pivot hole then weld in a new pivot tube.
Your pushrod is a stock modified unit.

Wow! That's great news, Mike! Makes me feel so much better about the braking system -- I'm so glad that you took time to read my post and look at the photos. I wonder if there is anything else on the car that has your name on it? I've visited your website and would be proud to have any of your parts on my car! FYI -- The 6602 Mk3.1 kit was sold in 2008 to a Ronald Brown in Wakefield, RI if that rings a bell. He did the majority of the work to get it to the go-kart stage before selling it to Dave Butler in Deep River, CT in 2017.
Again, thanks for time and interest in my car and everyone else's on this forum! I love the cooperative camaraderie!

So on the Whitby set up with a fox pedal setup is it plug and play?

Craig. Post some pics of the overall car. Lots of us old timers can tell you a lot based on pics.

Dave, does the whitby setup come with the spacer?

I believe that it did (MC spacers and small spacers for the booster). The spacer from replicaparts.com did not come with the kit. The power brake kit was a complete kit that had a lot of parts and thought put into it.

So it looks like even with the spacer the bearing would need to be moved inside, is that right?

Yes. Don't pay attention to the title of the blog posts I'm attaching. The frustration was fresh in my head. But you have the advantage of doing this after someone else's frustration of figuring it out.

Well i have been waiting for the whitby brack kit for over 6 weeks now, it was supposed to be 2 weeks! I'm thinking about going over the counter, anybody know what booster and master fits best without machine work?
Thanks

CFranks, did you need to move the steering bearing to inside the footbox with your booster?
Sorry to bug again!
Thanks

Yep, had to move it inside the footbox as do most people. I also had made a 3/8” spacer to go between the booster and footbox to locate the pedal properly, but even with that still needed to move the bearing. Was kind of a pain for me since the car was fairly far along, had to loosen the steering rack to get enough play to pull out the steering shaft. Few free to PM if you want to talk on detail what I learned.
Thanks, i have the e-steering and taking it apart is a pain, but am trying to get all the parts i think ill need.

Not CFranks (...) but I'll respond since I installed one of those too. Not really practical to move the splash guard. Common solution is to cut a clearance hole. Only sticks through an inch or less. Then attach some kind of cover to the splash guard if you prefer. Ask Jeff Kleiner about the official dog bowl mod. Another of his innovations.
