Just playing "what if" games online with part vendors... different part numbers come up on S13 & S14.
Hmm.... most likely the same bore, but the outlet line could be in a different location. Ditto on the RB clip. I suspect all three clutch master cylinders are the same diameter...
As to "pedal swapping" -- look up underneath the dash at the pedal box. Quite often the pedal box was the same between the MT or AT.... just a matter of adding the clutch pedal, and changing out the brake pedal (not as wide on a MT).
Could the RB pedal box be used? Seems reasonable, but I would not expect a "bolt in" operation.... then again might be worth a try. Obvious the RHD metal clutch line would have to be replaced.
