Anybody have a picture or diagram showing where the linkage attaches?
Original AC brakes use a bracket that crimps around the pedal. The linkage is usually up high as in illustration.
Here is similar location on the brake pedal, a welded piece to hold the rod and clevis pieces.
Steve, do you plan to use the direct pull setup shown above, or do you plan to use the pedal with a pushrod and a vendor supplied equalizer setup (or an equalizer of your own design)?
If you use an equalizer, the tab would be welded to the bottom of the brake pedal, like shown in this thread:
New AC, with Richard Baughman's linkage. It uses both pull rod and a push rod.
This picture that comes with the linkage shows the pedal. It looks to me like the pull rod attaches about 1½" to 2" from the center of the pedal shaft, and the push rod about 1½" under the shaft. But in the picture we're looking down at it from an angle, so those guesses may be off. Ideally, I'd like to have actual measurements and avoid the guesswork.
Here is a picture of the weld-on tab that I got as part of the vendor equalizer kit (I didn't use the tab because I bought a ready-made Rocky Mountain pedal that had the tab as an integral part of the pedal).
The tab is just under 2 inches long, 1 inch wide, and 1/4 inch thick. The center of the hole is 1 5/8 inch from the end of the tab. The hole is 5/16 inch diameter.
I'll be happy to mail you this tab if you want it, I have no use for it.

Why weld anything? The clamp goes around the pedal as shown above.
I failed to mention, Dan McEachern makes that pedal clamp, or did at one time.
Why two rods???
From an email I got a year or so ago from Richard Baughman, the maker of the linkage:
"The two rods from the brake pedal to the bell crank are...top rod for brake actuation and... lower rod (with spring ) is a push back assembly, to prevent brake drag. The push back spring assures complete brake release when you take your foot off the pedal."
I could make my own clamp. But if I'm welding on a piece for the push rod I might as well do the other piece while I'm at it. The question remains: How far from the shaft should the two holes be?
Steve - If Rich Baughman made the linkage set, wouldn't he be able to provide the correct measurements for where to weld the tabs on?
Good thought. I'll check with him and see.
Mine was welded as high as possible without hitting the slightly relieved floor boards.
Here's a photo of the original brake linkage.
