Don't worry about 15/16.
Use a 1.0 in mc and under your pedal build a stop; on my old race Porsche we had them under the cluthc and gas pedal; just a large headed hex screw with a jam nut. after you measure the throws or find exactly when the linkage was full open just screw the bolt up until it stops the pedal at that exact postion and lock the stop screw down with the jam nut. For the clutch I would stroke the pedal until in released completely then add about 1.0 to 1.5 more pedal travel until I hit the stop. Just measure to insure you still have margin on the .700 in total limit. Once you sort it out, it's simple and idiot proof.
Your experience with internal TO's is why I use external only. Easy to fix, don;t have to remove engine; and the biggy, you don't ruin a disc with fluid.
