Wrong Master Cylinder?

-The KH m/c on my 71 Demon parts car was a big-n-little. I parted it out in about 75. Since I was 3rd owner, I can't say it was original. I rebuilt it and ran it on my clone S for a while, but decided I wanted a smaller bore. I mothballed it in about 2002ish. I like the feel of the replacement,15/16 bore with a 73 booster.
-The KH m/c on my 68 Formula S car is also a big-n-little. It came into my possession in 1998. It had been languishing in the bush for over 20 years. The original owner crashed and rolled it and died shortly afterwards. I am 3rd owner on it too, counting the bush-owner I bought it off, who never did anything with it.
-The KH m/c in my 70 Swinger 340 was a big-n-little as well. I bought that one in the fall of 1970. I was 2nd owner. That car had about 11,000 miles on it when I purchased it from a slightly older than me fellow who had just become a father, and needed the money,of course. I still remember the serial number!
-The KH m/c in my 70Duster was a big-n-little. I bought that one as a roller,complete less engine. I only owned it for a short while as someone came along and made me an offer I couldn't refuse.
- My 1969 FSM, shows the KH m/c to be a big-n-little; page 5-56.
