This really doesn't answer your question, but just an option to consider, and you may have already done this, but just to mention it to be sure….. depending on the brake and clutch pedals, brackets, and pushrods, you may be able to adjust the position of the brake and clutch pedals relative to each other and to the accelerator (ie., closer to you or father away, fore and aft). While this still won’t give you the lateral distance between the pedals that you may be used to, it can provide a much more assured feeling of which pedals your feet are on at any given time and give you a higher confidence level that your feet are where you want them to be.

For instance, adjust your brake pedal distance so that you can keep your right heel planted in one spot. Then when moving from the accelerator to brake pedal, all you have to do is pivot and twist your foot instead of lifting it. The best spot will probably be with your brake pedal slightly “higher” than your accelerator. Low enough to the accelerator so that you can pivot easily, but high enough so that you won’t be depressing the accelerator when hard on the brakes, just in case part of your foot is still over the accelerator.

For the clutch, you will want to have it noticeable “higher” than the brake pedal, just to give you a distinguishably different “feel” for the clutch pedal position so your left foot will know it is in the right place.

Check to see if you have a threaded pushrod threaded into a clevis attached to the pedal arm and locked in place in the clevis with jam nut. Loosening the jam nut will allow you to turn the pushrod (may or may not be a little resistant to turning). You will see the pedal arm move as you do this. If your brake light switch is activated by the brake pedal arm, you will probably need to readjust this as well if the brake pedal arm is moved.

As mentioned above, you may have already done this, but if not, it really can help with the feeling of what is what down there, and be more comfortable in that regard. What was comfortable for the previous owner and what he was used to may not be right for you at all. And this would be well worth trying before going to the expense of making transmission tunnel changes, and all of the pedal, throttle linkage, master cylinder, hydraulic line, etc., changes which would then be needed to make use of the space.
