Master Cylinder

yep, they are the same master, or at least they look the same. I got mine from a brake only supplier that used to be in Ann Arbor called S&H Brakes. I too questioned whether it was right, but they knew all about the K-H system and assured me it was the correct unit. I don’t know the part number or make, it was some time ago when I got it.

I actually have a couple packed away. Not accessible for a few years after I move. They are cheap enough on Rock Auto. I did purchase a Proportioning valve for KH brakes after reading an article about it, still running a drum brake proportioning valve with 1974 Disk MC . Works decent but not great. If I get more time to work on it I want great .
