The clutch pedal is about 2" higher then the brake peddle on my car and it is driving me nuts, I changed the clutch, pressure plate and throw out bearing and the car shifts fine. When I try to adjust the clutch to lower the pedal I can't. I have looked at a lot of pictures and it seems that the pedal is high on most of the cars. What I was wondering is has anyone made a shorter clutch rod from the pedal to Zbar to lower the pedal?

The length of the rods has absolutely nothing to do with the height of the pedal (they are to adjust the free play in the pedal), there should be a stop on the pedal up near the main piece that bolts to the firewall and dash, it could be bent, it could be worn, someone may have installed the wrong year pedal. All the mustangs had a 3 finger clutch which means they have a clutch assist spring up under the dash and a clutch return spring, I am assuming they are there and working since the pedal is coming up. So you will have to look closely to find the stop. Here is a picture the L shaped piece near the pivot will hit the stop. :http://www.mustangdepot.com/OnLineCatalog/Transmission/images/MD-402-6970M-C.JPG
It could be if there was a cushion type material there it is gone now and allows the pedal to come up too high. Here is a website that shows how to install a adjustable clutch stop: http://www.mustangsteve.com/fyi_brakepedals/msFAQbrakepedals.html
Post your results. Good Luck.

Thanks for replying, The springs are all there and seem to be ok, I did replace the rubber stop on the pedal bracket but the pedal is still to high for me, I also tried removing the stock rubber stop and install a bolt and nut this allowed me to adjust the pedal so that it is perfectly level to the brake pedal, but when I did that it caused the throw out bearing to be to close to the pressure plate. I guess it's time to pull the assembly bracket out and inspect it closely and and rebuild it.

Bill; about thirty years ago, I had the opportunity to buy and install a set of Mach seats and carpet into my '69. While I had so much room (no seats) I took the time to stick my head under the dash. I was totally tired of the uneven pedals. My fix was a hood bumper filched from another (junked) car which I threaded into the hole on the outboard side of the swingpedal bracket. In Rex's thread to MustangSteve; I see that hole on the '69 bracket but not on the '70 unit. All I can say is it worked for me.

Once you get the pedal height with the stop set, then you need to adjust the rod for the proper amount of free play, usually 7/8"-1 1/8" if my memory is right, really any free play is good, it keeps the throw-out bearing from being in contact with the fingers on the clutch pressure plate, which would cause premature failure of the throw-out bearing. One of the biggest problems I see, are people add additional floor mats and all kinds of other stuff on the floorboards and carpet, and reduce the amount of pedal travel, there needs to be enough free play and enough travel for the clutch to fully release it. Good Luck.

I was thinking the same thing with the hood bumper but didn't have one that's why I tried the bolt just to see if it would work then I was going to pick one up, it may be that I just didn't go back and try to re-adjust the clutch rod after I set the pedal height

Thanks again
