How to attach AC Pedals:

[TN] "The pedals need to be slotted to run a bolt through, and there is enough material around them to do so. On my clutch I have the pedal offset to the left to provide more spacing between pedals."

[Cemi] "I slotted mine with a hacksaw then cleaned up the waste with a drill bit. They are attched to the pedal box arms with #10 stainless steel nuts and bolts and shimmed with stainless steel washers (I bought a box of the bolts for the hood hinge). After I attached them, I got to thinking that you may be able to just drill a hole though the AC pedal bosses and attach them to the pedal box arms at an offset, without trying to notch them.
"

[RT] "I did mine with the pedals in the car, you will need a 90 degree drill adapter to drill the pedal cross holes in the arms, Harbor Freight has a nice one that goes on sale for $16, sometimes less. A cut off disc or sawsall will work to cut the old pedals off.

I milled 1/4" slots in the pedals, however you'll find that one arm is 5/16 thick, I ground down the arm end a bit with a grinder.

Takes a bit of time but the look is worth it.

I do think there is enough thickness to do the drilling and tapping thing if you wanted to leave the old pedals and mount the AC's to them, of coarse you'd have to grind off the lump in the back."

[RT] "I had a 1/4" slot needs to get milled in them and then a cross hole drilled."

[bo] "I used a cutting wheel and put a slice right down the center of the tab. Then slowly remove equal amounts of material from each side. Keep checking the fit with the shaft. You can always take more off, but, putting it back on is much more difficult. Keep the fit tight and you will be pleased. Drill a hole right through the center of the tab and bolt her down. I used 1/4 inch hardware. If your fit is too loose, the pedal will never tighten and you will crack your tab. Be patient, take your time and It will pay off. Also, on the brake pedal arm itself there is a notch. I ground the notch higher so the AC pedal would fit flush."

[1775] "I drilled my hole thru the solid block first. I was concerned about snapping the aluminum pieces once the center was cut out. Then I used a cutting wheel to cut out the center of the block. I ensured a tight fit by finishing touches with a hand metal file or a Wizard hand tool. BTW, I think I cut the brake pedal differently to move it slightly toward the clutch. I cut/ground one side of the block and put the bolt through. If you make it too loose a fit, use small washers or you could snap the pedal mount."

[hk] "One thing to remember..... If you plan on doing this after the car is complete, you will need a right angle electric drill or a very short (distance from the chuck to handle) drill. It is relatively easy to drill the hole needed for the clutch pedal, but the brake pedal is a bugger."

Question: [SC] "I just modified my clutch pedal to meet up with the brake pedal. My question is, will I have a problem with not having enough clutch movement. Now it seems like there will not be enough movement to disengage the clutch. you guys let me know if there has been any problems like the one I think I'm going to have."

Comments:

[RT] "I moved mine 1" further back, that was the max with the old shorter footbox's , and it works perfect. It's also in line with the brake."

[PM] "I cut my clutch pedal off near about 4 inches from the top....then had a brake pedal from another mustang welded onto the clutch stub (thanks wade c)....I inverted the foot pads inward to give me a little more room ....the clutch is now about 1/2 inch higher than the brake and the travel is good and it seems easier to control.....i removed the door, seat, steering wheel and disconnected the clutch cable....take note of the quadrants travel with stock pedal before you cut it ....then drill a hole in the new pedal and stub tighten a bolt through it and with the cable unhooked triple check to be sure the travel is the same...then weld it...I like the look of the twin heavy pedals"

[SB] "I cut a small wedge out of the back of the clutch pedal arm to align it with the brake pedal. Don DuPontee was nice enough to "undo" this mistake for me. I can now disengage my clutch again."

Here's my pedals. I used AC pedals from Finishline and Russ' Gas Pedal Assembly. (see FFR Vendors)
