Here is the manual push rod and clevis for the vette master cylinder. I remember it is a bit long for the foot box. I used a stick to first measure then I trimmed the rod down a few inches. You might want to call them to verify the rod diameter is correct. I just did a search I think it is correct.

Here is a picture I took last year. I think I had to add a 1/8 steel plate to add a little extra metal to mount the master cylinder. I think the holes were not aligned just right.
Make sure you drop the holes down on the pedal to get more leverage. If you need I can go and measure mine. Manual brakes need a bit more pedal pounds of force. There is not much travel in the pedal needed so lower on the pedal you mount the clevis the more force you can apply.
